I have factory and full-house custom 10/22s, as well as AR22s. It all comes down to what you like and what you want to do with them. I have them set up for Rimfire Challenge, Precision Rimfire, hunting, suppressors, training, even a clone of a SWAT rig I built for a department many years ago to take out lights.
Both can be made just as accurate (about 1 MOA) out to 100 yards. But there are trade offs and magazines, chambers, etc, must be balanced against purpose and cost. Black Dog mags are readily available for the AR22s, as are bolts and barrels, all else is AR15.
In CA, the 10/22 is going to be a little less stressful as the 10 round magazines are everywhere. Since you seem to like them a little more, go that way. I build all of mine these days because I want specific parts and I want to fit and test them. While I am sponsored by Tactical Solutions, they are what I preferred prior. My most recent build I used a PMACA long nose chassis with a Kidd barrel, everything else TS, for a precision build. They make some great take-downs and parts if you want to build one just like you want it.
