Need some advice on a S550 trans config

[speedknot]

I currently have a beautiful 2014 GT 6spd manual. I've had some suspension work and other things done to get it ready for a supercharger. Unfortunately, due to medical reasons, I'm finding it more difficult to use the clutch now. So its time for an auto trans. I still plan on installing a supercharger on my next stang, but I'm debating whether or not to go with a 6spd or 10spd auto. Does anyone has any tech insight on these two trannys and which one would be better suited for a Roush Ph1 or Ph2? I may track it in the future, if our local govt allows it again.
Thanks in advance

The 6 speed is tried and true. Lots of info on them. The 10 speed is faster but has only been in mustangs since 2018. There are plenty of GTs that have had their issues with them at stock power levels.
