Using a mechanical keyboard for the first time. I went with a Logitech G170+ and FFS, I can not get used to this thing.
Maybe it's because I'm just so used to using my old keyboard, but these keys feel really small and I find myself accidentally hitting multiple keys at the same time. Especially when I reach for the numbers. I can normally hit any number without looking but now when I reach for 3, I hit 123213.
Also, because this keyboard is so thick, my thumbs rest at the corner of the space bar whereas on my old keyboard they rested on the top. So pressing the spacebar on this thing after typing for a while starts to hurt like a bitch. I actually had to wedge something under the wrist rest to elevate it so so that my fingers rest on top of the spacebar again.
That said, I do really enjoy the feel of mechanical keys. This board uses browns, and they felt like the best compromise between feel and noise. I don't like blues. They're just too loud and I can imagine my wife complaining about that.
I know I'm going to be stuck with whatever I buy for years and for $100, I had better be in love with it. So I may end up returning this and trying something else...

I have the Corsair K70 RGB with browns (I also find them to be the perfect balance of noise and feedback) and I absolutely love that keyboard. I find the size to be perfect (I guess it's considered a regular sized keyboard) and the added wristpad also feels nice and relieves the pain I used to get after long sessions behind the keyboard. You might want to try it out, if possible (the non-RGB K70 is exactly the same, but cheaper and only comes in red lightning).
