My journey went from using membrane keyboards (not knowing there was anything else available), to finding out about mechanical keyboards after watching a game streamer and his clacky keyboard, to going out and buying one...only to find out it was a membrane keyboard that was marketed as mechanical-like (!). After a few proper mechanical keyboards (trying to chase the 'thock'), then to low-profile, I'm now on a low-profile split mechanical keyboard, and I think this format is end game for me. The split helps a lot with ergonomics and just feels so natural, and the ortholinear setup just makes sense, despite the few weeks it took me to get used to it.

I was skeptical about the split keyboard, and living in an area that has no stores where I could try it out, I ended up buying a relatively cheap one from AliExpress. I swapped in my own switches and keycaps, and now it feels amazing to type on.

Being able to lean back on my chair while typing with each side sitting on the arm rest is amazing

My back and shoulders felt so much better when I mounted my spliit keyboard floating under my desk, halves shoulder width apart. Not just arms on the armrests, shoulders back against the chair instead of rounded forward. I can't go back. Nevermind that typing that way with colemak and hardly moving my fingers feels like magic.

"Low-profile split mechanical" is I think my ideal too. Though I really like cupped keywells, the Advantage2 definitely convinced me that it's more comfortable than flat.
