there are two aspects you need to consider when pondering which bike is best for you - playfulness and assistance.
The SL is way better in agility and overall feel. You can move the bike so much better, but compared to the full levo the assistance difference is significant.
I have both, andif you asked me a few months back if I had to keep just one, which would that be, I’d answer the full levo. Today I have a different opinion. If you’re fairly fit, I feel like you’ll have more fun on the SL. Sure, it depends on what kind of trails you ride, but the more I ride the SL the more I like it.
