Until now, the clear competitor to Focusrite Scarlett has been the MOTU M series. The one very useful thing they all have in common though is a loopback mix function. I use this all the time on my M2, and it is quite rare on interfaces. I would say that specs-wise, the AMS does not appear to be quite in the same league as Focusrite and MOTU.
One other thing I noticed looking at the specs is that the AMS-22 has a different preamp compared to the others in the series, and notably has a low max mic input level. That's probably fine, as it's intended for podcasting.
