i think the extra crop that the p21 does would drive you mad. the a22 will still be a big crop, but nearly as much.
i had a a22 for a while (with an h) and its a nice back. quick shooting and nice files at 50-100 iso, 200 tolerable and 400 un-usable unless you are throwing on grain in post.
doesn't the p21 require a wake up cord or something on this camera? a22 won't.
c1 is the best software to work with, so best to check if the older apt us backs will work with it. i know the newer leaf backs do.

The 645 film crop to an Aptus 22 is 1.16 to a P21 is 1.26. Not much even on an RZ and every digital back is going to look small on an RZ.
I'll admit I like the slightly extra territory of the 1.16 crop but after a while it doesn't really matter and you get use to the 1.26 format.
I've owned an Aptus 22 for a year, a P21+ and a P30+ for multiple years and the Phase backs never went into the shop for anything, the Aptus went in 4 times for overheating, lcd replacement, overshooting then jamming and centerfold.
Now in Leaf's favor they were kind enough to make all the fixes eventually, (the overshooting took a long time before it was acknowledged, but the rest were done quickly through (then) Leaf Of America.
The Aptus 22 was a stop slower than the P21, had an effective use about 1 and 1/2 stops less than the P30+.
I do think the Aptus had a nice look when processed in photoshop, in my view less so in LC 10, 11, etc. and I've never tried it in C-1 because I sold it before Leaf was acquired by Phase.
Tethering finally became better in lc11 though never as robust as C-1.
I like the interface of the Leaf Touch screen better, but didn't like the fact that it cannot power itself when tethered, the battery use, the fact that the battery hung down out of the back of the camera and the fact you can't see the image on the back of the camera when tethering.
I find the last part maddening, even though the lcd's on medium format backs weren't at the time that good, it at least let you see the composition of the image without running over to the computer station.
I also found the aptus 22 a moire machine, on a lot of garments, things the p21+ didn't see as much, the p30+ never saw.
For processing the Phase files go into about anything compressed or non compressed, the Leaf files have to be decompressed before going into lightroom.
Actually, unless you shoot fast I'd look for a good used p30+.
IMO
