Started with Razer Black Widow Ultimate with "Razer's" green clicky clones. Going from the rubber membrane of a generic Dell giveaway keyboard to the BW was a game changer and it started me down the path of looking down on every keyboard that was not mechanical.
Fast forward, I start learning about MX switches and learn about reds and browns. All of a sudden the thin, high pitched click of the Razer greens (aka blues by another mother) were not my favorite. Still didn't care for the reds as I was a tactile guy and felt like the reds were all about bottoming out. Not to mention reds were entirely too light for my liking. At least that's what I thought at the time. My next foray was a used Filco Majestouch 2 with Cherry MX browns. All of a sudden I had a chassis with superior acoustics and a heavier, more appreciable stoutness to the board and I was hooked. Browns became my new thing. Picked up a Cougar Puro TKL with reds because I liked the fact that it came with a magnetic keycap protector/dust cover. It now awaits switch transplant.
Then...and here's what really set me down the path of spending what I now consider dumb time and money into keyboards: Anne Pro 2 with Gateron browns. Holy crap. Could not get enough of the space bar thocc. Could not get enough of the light show. Could not get enough of the BT and portability. Immediately wanted to try the other options so I picked up another model with the Kailh box browns. All of a sudden I had a board with MX browns, Gat brows, and Kailh box browns and was surprised to realize how different they all felt to me. Started looking at other high quality manufactured boards. Couldn't pull the trigger on a Leopold but was tempted for quite awhile regarding the Ducky One2 mini.
In the midst of this I started to find YT channels talking about how people modded their keyboards. Changing keycaps, lubing their stabilizers. Regretfully made silly purchases such as a WASD set from Massdrop which were laser ablated ABS which didn't match the other keycaps at all and looked horrid. There goes $20. Then a custom designed TKL set from WASD keyboards that were thin printed ABS. Wasted $60. Started doing more and more research about keycaps.
Fast forward to GH, r/mk, r/mechmarket, etc. Discovered Taeha Types. Discovered Chyrosran88. Proceeded to spend HOURS listening to various combinations of switches, caps, boards. Watched every single one of Thomas's keyboard reviews at least twice.
Blah blah blah, another Anne Pro 2, a Tofu60, DZ60+keyboardbelle kishsaver, Vortex Vibe, Lexmark Model M, Apple AEK, AEK2, IBM M122, IBM F122, F62, F77, Ducky 2, Ducky 3, Fujitsu rubber membrane, Maja, Space65, NMB dome with slider board, HHKB, Niz clone board, GK61, M0110A, U80... then down the switch rabbit hole: cherry mx clear, mx green, mx red, mx blue, mx brown, mx pink, gat brown, milky yellow, yellow ink, silent alpacas, YOK trash pandas, Zilents, Sakurios, TTC Gold, Holy Pandas (controversial ones), Boba Gazzez U4, Royal box navy...
So where did I land? I used to like loud, clicky tactile switches. My 3 keeb mainstays at this particular moment: Vortex Vibe with lubed Sakurios, Tofu60 with stock Zilents V2, and F77 capacitive buckling spring. That said, if you were to give me most any mech board with mx browns and properly tuned & lubed stabilizers, I would be juuuuust fine.
