I upgraded all of my breakers to AFCI+GFCI. Worked flawlessly so far (about 6 months in).
The only two times where my AFCI tripped were 1) my blow-dryer shorted out due to a worn out cable (WAI) and 2) the PSU on my PC started tripping the AFCI (sent back to the manufacturer and got a replacement). So in both cases, at least for me, the AFCIs caught real problems.
Not a single trip of the GFCI function so far including vacuum, fride, and various power tools (and it's great peace of mind to have this with kids in the house).
All good for the average user. You cannot run a saw or other corded power tool off an AFCI breaker. it trips _constantly_. This is a problem because NEC wants AFCI/GFCI in all rooms with concrete floors, like garages. This means you basically put those plugs in to pass and then pull them out again.
