Surface Studio 2 vs. Late-2015 iMac for video editing?

Hi–

For the longest time, I was a diehard PC fan. Since trying out a Mac a couple of years ago, I now do much more work on the Mac. I recently purchased a Surface Studio 2 (the middle one, with 1TB). I’m starting to do some basic video editing, and wonder if my late-2015 MAC (base model) will be as efficient as the Surface Studio 2, which is much newer. I can find all sorts of comparisons to the 2019 iMac, but (understandably) not the late-2015 iMac. Does anyone have thoughts on what system should be at the center of my video editing activities? Thanks in advance for your suggestions.

Cheers, Brian
