The Fatty is user serviceable and very simple to do so. PPS sells rebuild kits for Fatty and Stabilizer.
The main difference between the 2 is that the standard Stabilizer is adjustable from 0-750 psi output pressure and the Fatty is a low pressure system regulator adjustable from 0-400 psi output pressure. With that being said both will work great for you and I haven't heard of one being particularly more fine tune friendly then the other but since the Fatty is a smaller output range regulator I suppose it could allow for more fine tuning. It really comes down to which you like the look of better.
