Other people's recommendations are fairly meaningless in this context, this is an entirely subjective decision. Buy the keyboard with the keys you use, then decide whether the space savings or ergonomic changes justify cutting out the keys you don't. I go TKL because I rarely use a numpad outside of work and favour the extra space on my deskpad for mouse movement than I do having a numpad on the few occasions I use it. But I use my arrow keys extensively, so any recommendations to 60% make zero sense.
It has special buttons for music, voulume, programs, back and forward buttons etc. that I never use.
Depends on your needs/wants tbh.
