Autofocus tracked a toddler at a birthday party without missing a beat
I shoot events for a living and this body's eye-AF locked on through a crowded room. Files came out of the card clean enough that I barely needed to touch exposure in post.

Upgraded from an older DSLR and it was worth it
Low-light performance at a wedding reception was noticeably better than my old setup. Battery got me through a full 8-hour shoot with one spare in reserve.

Excellent body, buy the extra battery
Image quality and build feel genuinely professional. My only note is that video mode drains the battery faster than stills, so budget for a second one if you're filming.
