I know the pro is a lot more involved in terms of what you can do with it. @dancing james has a pro I think? And seems to be pretty good at utilising features of these things so will likely have more info.
Personally I've never looked back after starting to use gas, but my enthusiasm for doing anything but pizza in my Ooni 3 is pretty low (simply because whenever I want to get it out, I want to just make pizza).
TBH I tried Wood twice and switched to gas... quicker, easier and more consistent.
