It's not just you lol. Some people are complete keyboard snobs. I prefer a mech but yeah typing on those chicklet keys sucks. Even on the better ones, to me anyway, it feels like I'm just mashing my fingers into a slab lol.
Sure, the type of keyboard you use, and especially the one you're used to, makes a difference.
Not sure if a keyboard snob, but I changed a lot of keyboards and even when technique is more important, if you type a lot, mechanical keyboards with linear switches are very fast and you won't get tired typing with them.
My average speed now is about 85 WPM, but... it took a lot of practice (started at 45 WPM)
