Hi Greg - I have just finished rebuilding my Observatory and have upgraded my primary imaging camera from a ST8 to a ST10 - My telescopes are Mewlon 250 and a 120mm Refractor. My secondary camera is a ST8300.
The primary advantage of the ST10 is that it has 3 times the well depth and from 400nm to 900nm it has nearly twice the QE of the ST8300. It is a NABG chip but the well depth is that great (75,000), that used sensibly it is not a problem plus there are a number of software applications that handle the problem easily.
The high QE% of the camera gives it sorter exposure times with the refractor - especially in the HAlpha range and intelligent use of binning lets it really capture the detail of the smaller galaxies.
On the negative side it does not have the acreage that the newer ABG chips have. I originally bought the ST8300 with intentions of using it on the M250 at f10 by binning it at 3x3 but the ST10 binned 2x2 stomps all over it in results.
Cheers
