There's no right answer here. As other people said, taste in tactile switches is a personal preference. There's a lot of different tactile switches, and a lot of different tastes in tactile switches.
Some parameters by which tactile switches vary include the following. A lot of these you can ascertain from looking at the force curve of a switch.
ThereminGoat has a good write up on how to read a force curve here.
- Size of bump. The level of tactility ("more tactile" vs "less tactile") of a switch refers to this, and is the height of the bump on a switch's force curve. More tactility means that it takes more force to get past a tactile bump, and results in a more intense "collapse" after the bump. On one side, you have a switch like MX Browns which has a relatively small bump (about 10gf), and on the other side, you have say, a Kailh Box Jade, which has a ~30gf tactile bump. A lot of the popular tactile switches in the community these days (e.g. JWK T1's and Holy Pandas) feature ~20gf bumps.
- Location of bump. Tactile switches usually place their bumps either at the very top of the stroke (e.g. T1), or towards the middle of the stroke (e.g. MX Clear). Some switches like the Boba U4 and NK Blueberries have the bump occur over the entirely of the stroke, but the peak on those switches is usually in the middle.
- Rounded versus sharp bump. This is hard to describe, but the transition from "build up" to "collapse" is more sudden on a sharper switch and a bit more spread out over the stroke on a more rounded switch. Switches like Boba U4's and NK Blueberries that spread the bump out can be described.
- Spring weight. This is generally measured in the force it takes to bottom out, but that doesn't tell you the whole story, since springs have different initial force (which tends to be described as "slow" springs for springs that have high initial force at the top of the stroke, and "fast" for springs that have low initial force). A "slower" spring is heavier over the course of the stroke than a "faster" spring even though they may take the same bottom out force. Generally 60-70gf tactiles are most popular, and most poplar tactile switches are around that range, though there are heavier ones (e.g. MX Clear is 90gf bottom-out), and many tactiles work fine with lighter springs. This is a personal preference - people that prefer lighter springs tend to find that they type faster on lighter springs, or don't mind (or even enjoy) bottoming out, or find typing on heavy springs fatiguing and tiring. People that type on heavier springs often type harder naturally and want to avoid a harsh bottom out, or want to avoid bottoming out, or may find that they type faster on heavier springs because they "boost' you on the return stroke.
You also have silenced tactiles (e.g. Zilents, Boba U4's) which have soft dampeners on the stems to quiet the bottoming out and return, and switches also vary in terms of smoothness and sound. Generally, nylon is associated with a deeper, "thockier" sound, while polycarbonate results in a higher pitched, more "clacky" sound. Polycarb is also generally transparent (good for backlights) and often smoother, so there's a lot of tradeoffs here.
In terms of some switches to try that are generally considered good:
- T1's - these have a slightly rounded bump at the top of the stroke, are pretty tactile, and come in 62g and 67g usually. Pretty smooth too stock. Kind of clacky sounding though.
- Holy Pandas - I haven't tried these personally, but they're widely recommended. They're quite tactile, and have a bump at the top.
- Kailh Box Royal - I also haven't tried these personally, but these have a sharp tactile bump at the top.
- Cherry MX Clears. These have a relatively sharp bump towards the middle, and have medium tactility. They're often considered heavy, and are basically designed to prevent you from bottoming out, and have a medium-heavy actuation force (~65gf) and a very heavy bottom out (~90gf). Kind of scratchy stock. A lot of people swap in lighters into these.
- Boba U4's - these are silenced switches with a large tactile bump that's spread out over the course entire stroke. Come in 62g and 68g. Very low wobble. I'm personally not a huge fan of these (it's basically impossible to not bottom out in these), but they are nice switches.
A lot of these switches you can buy in fairly low volumes to try out. I personally like to buy 4-10 switches, clip them into a plate, and put keycaps over it and try it with 4 fingers so I can get a feel for them.
For clicky switches Kailh's clickbar Box switches are still generally considered the best, and they all have very sharp tactile bumps in the middle of their bump. Box White/Pale Blue has the smallest tactile bump, Box Pink kind of in the middle, and Box Jade/Navy has the largest tactile bump.
I have the same views on HungerMechanic in terms of (good) rubber domes (e.g. Dell Quietkey RT7D5JTW, Lenovo KB1021) actually being quite tactile, and the main advantage of mechanical switches being that they do not require bottoming out to actuate. However, I reach the opposite conclusion in terms of what switches I want. Since I don't need to bottom out, I want a relatively heavy switch with the goal of avoiding bottoming out or cushioning it (as I tend to find bottoming out harsh and unpleasant), and want a fairly large tactile bump to let my fingers know that I've actuated and move on as soon as possible. My current favorite switches are Cherry MX Clear switches with an MX Blue bottom housing swapped in, which increases the tactility, and the stock 90gf MX Clear springs, with lube applied to increase smoothness and switch films applied to reduce the wobble on the top housing and to improve the sound. I'm also going try MX Clear stems in Boba U4 bottom housings and Outemu Sky top housings, though I'm still waiting on those parts to come in.
