NEX 6/NEX 7 AF Tracking ? As good as entry level DSLRs?

Hi guys, I'm considering switching from an attention whore DSLR to something less "pro" looking...

9 times out of 10, I shoot stationary objects, which is why I never cared that I had "entry level" AF in my Canon T2i.

OTOH, I do like to shoot friends at parties, who move around, etc.

Will the NEX 6 with the PDAF and the NEX 7 track, as effectively as my T2i? (16-50 PZ is the lens I plan to get for either NEX)
