I have both. Two different animals.
The Sawstop compact is ok. Geared fence is much better than the bigger "mobile" version (owned, sold to buy the compact). The lock for the fence is super tight on mine. Everything else is ok and does it's job.
The Festool tablesaw is very enjoyable to use with the exception of the fence which is mushy and fiddly to adjust accurately. Huge fail there, but I find the other features overshadow that fault. Batteries are mostly non issue, but I have extras.
All that being said, I am willing to set up and leave the Sawstop on a new construction site and will not do that with the much more expensive to replace Festool. I have an upcoming week on a 32nd floor remodel finish which the Festool will be a boon for.
In summation, the Sawstop compact is a decent all around workhouse, the Festool is a excellent swiss army style tablesaw with one flaw that can be overcome with diligence.
