Hmmm... I have a bunch of SB3s, and its pure marketing BS to claim an unmitigated victory for SB3s over AEX. Sure, SB3 may have a small remote, but with the small remote comes small UI and small functionality. You use the AEX in conjunction with an Apple laptop and while your "remote" (i.e., the laptop) is bigger, its got a helluva lot better UI and functionality.
That said, SB3 is built with semi-audiophiles in mind, so the parts quality is rumored to be better--you get digital coax out, for starters, whereas you are limited to toslink for AEX.
They just serve different purposes, one isn't inherently better than the other. For my main rig, I use something more analogous to the AEX route UI-wise--I actually use a superquiet SFF standalone PC/USB audio device in conjunction with a touchscreen airpanel--but in rooms where music is more for background atmosphere, I'm happy using SB3s.
