Both good choices.
A semi-funny with the SL2 - I chose it over the T7i mostly for the compact size. That worked against me once on the trip out West. Put even a medium lens on it with my light "travel" tripod, the body is so light the rig wants to tip over. It was extra-windy on one shoot of the semaphores. Train was coming, I had everything going, stepped away for a second, and the wind started to push the whole mess over. I caught it before the expensive bits hit the ground, but the resulting video is funny once you realize what happened.
