Honestly, recently I've consistently noticed Firefox running faster than Chrome for my usage scenario. It might be bias, but I find browsing on Firefox a more enjoyable experience and uses a lot less of my system resources.

I stuck with Firefox through the times where it was much slower than Chrome for idealistic reasons as well, but now I feel like speed is less of an issue because they are both pretty even.

It might be a placebo effect, but I find that I switch back and forth between Chrome and Firefox every 6-12 months after the one I'm using feels slow and the other feels faster. Maybe they're actually leapfrogging each other in performance, maybe not. I'm currently on my Chrome phase.

One thing that I think could be an interesting variable is how many tabs you've accreted. Browser A with 100 tabs open versus Browser B with 1 tab.

I don't go crazy with tabs and I like to clean up my tab bar by closing old tabs. It's rare that I have more than 20 at a time open.
