Some may scoff at me, but my favorite is Cherry Brown. It must be lubed however and I swapped the Springs for Sprit 62g springs- the resistance, bump, and sound is perfect for me.
I now have a hotswap board so I can more easily try new switches and am itching to do so. What kind of LIGHT tactile are people liking at the moment.
You seem to prefer tactiles that are slightly heavier than MX Brown [e.g. 62 G Ergo Browns, Durock Light Tactile].
People have already listed some tactiles worth trying [e.g. SP Star Meteor Orange / Duck], so I won't go over those.
Some 'heavier / stiffer Browns' are:
-TTC Watermelon Milkshake [feels like a Brown with a heavier spring, I like to replace it with a 63.5 - 65 G Progressive spring]
-Kailh Pro Purple [lube it with 3204, and for an interesting variant try a 63.5 G Spirit spring]
-Gateron CAP Brown [this is a factory-lubed Brown using Gateron's new CAP architecture. Supposed to utilize lube better or something. Non-standard stem and spring. They are already lubed, although they benefit from lube in the leaf area].
--------------------
There's also a category I like to call 'light-medium.' They are more tactile than MX Brown, but perhaps less tactile than a 67 G, barely-lubed Ergo Clear or 65 G Durock Medium Tactile.
-Everglide Jade Green. [Not well-known. They need heavy lube, 3204, especially in the leaf-area. And they need to be filmed, for sure. But once you do that, it is like a top-mounted, slightly heavier Brown. You might particularly enjoy it with a 62 G Spirit spring, which I have tested].
-Zealio V1 Redux. [They are finally back! Bone-dry from the factory. You need to at least lube the stem with 3204 or 205g0, or get creative and selective (better results). Surprisingly-good with 60 G TX 14mm springs. It's like a secret recipe.]
-You could almost call the Dragonfruit a light-medium. It feels like it's on the lighter end of the Durock Medium Tactile variants. Desperately needs lube, and probably films if they help. At least lube the spring. Benefits from OUTEMU tight-tops, which reduce some of its problems.]
--------------------
In terms of medium-tactiles, there are almost too many to list. Ergo Clears could count here, although I build mine as light-medium.
-Durock Medium Tactile has many variants. Mode Signal is one of the lighter ones. Penguins are the same weight, but there many be subtle differences in how the stem interacts with the leaf. Comes unlubed, so you have to lube it. You can put an MX Clear stem in the Penguin housing, lube only the legs, and get away with 60 G springs. Taro Ball are nice, but they are a little heavier. Durock Cerulean is supposed to be one of the closest to a traditional Ergo Clear. Don't know if that's true.
-Naevies are relatively new, with the Naevy 1.5 being the current offering. They are supposed to be a factory Ergo Clear, using different materials. Looking at the spring weight, though, they might be a light-medium. They might, in fact, be lighter than Durock Light Tactile.
-SP Star Magic Girl is a medium tactile that has its adherents.
-TTC Pale Blue is something every tactile enthusiast should try. It's a crisp, medium tactile on the higher end. Not MX Brown-shaped, it's more 'traditional' if you ask me. Like something you'd expect from a 1970s keyboard.
-SP Star Purple is like a slightly toned-down T1, I think. Smoother and better-sounding stock.
-The Huano Banana might be the aforementioned Ajazz Banana. It is definitely a fun switch. It's like someone bred an MX Blue with an Ergo Clear. A very snappy Brown-like tactile.
-AKKO CS Sponge is similarly a snappy medium tactile.
--------------------
Then there's silent tactiles. You probably already know about Zilents and U4 Boba, which are heavy-tactiles.
But there are also some silent light tactiles. And I don't just mean Gateron Silent Brown.
There's Aliaz, which is the least-tactile of all. They don't need lube. But the springs are terrible and should be replaced with lubed TX. The 14mm 65 G is a good weight.
Silent Sky / Forest was meant to be a silent Ergo Clear, and it's about the same intensity. Put the stems [which you can buy separately] into Cherry or TTC Brown housings for low tactility, or Huano Banana / AKKO CS Sponge for more tactility. Or Boba housings for max. tactility].
Kailh Silent Grey is apparently something that is real, and I know that OUTEMU has a silent grey for sure.
Now there is something called OUTEMU Silent Lemon, which is really cheap. You might be able to get away just lubing the spring, but I hear people also lube the leafs and stem rails.
Kailh makes a BOX Silent Brown, which is like a Zilent V2 in tactile shape, but not quite as intense. Cheaper, too. If they are too tactile for you, just put the stems in a BOX cream housing.
--------------------
So those are some light and medium tactiles to try, in addition to what others have already written.
If you like, I can also give you recipes for frankenswitches.
On the other end of the spectrum, the least tactile switch I have tried is the KTT Mallo. They need lube on the springs and leaf area at a bare minimum, to reduce noise [they are smooth stock]. Very cheap.
There is also something called an AULA "Matcha Shaft" that is $23 for 110, said to be like MX Brown or a light-tactile. [From AliExpress]. Gateron Orange is also very low in tactility, as I think it is a factory-lubed Gateron Brown. Uneven, though.
I'm set to receive some KTT Matcha, said to be a medium-tactile that is highly-regarded in some quarters.
