I use many different computers every day, and for the past 3 years, I have preferred 40% keyboards to get the job done.

Basically, the smaller the keyboard, the easier the layout is to remember. When it fits completely under your hands, with no extra columns or rows necessitating hand movement away from the home row, you can then commit the layout to your body's muscle memory faster. It then becomes more efficient and comfortable to use.

EDIT: On my current layout, I do something pretty unconventional, which is saying a lot considering I'm using Dvorak. So I've mapped the B key on my Mods layer to Backspace, D to Delete, T to Tab, and E for Enter (just to name a handful). Now, I prefer this to having mods requiring a long pinky reach to either side. It's also liberating using a layer for an extra level of intention before hitting stuff like Delete, Backspace, and Enter. If you're reading this, there's a good chance you've accidentally hit Enter one on a message or button when you didn't mean to. Especially if you've dabbled with HHKB layout. With this type of arrangement, worrying about that is a thing of the past.
