Will OCLP upgrades slow down my computer? Which OS should I update to?

2015 MacBook Pro 13\"

Hey, so my friend recently told me about OCLP, and I really want to experiment with it, but I'm just worried if it will slow down my computer or not. The only major apps I use are Arc, Zoom, and PowerPoint (I'm a student, and most of the things I do are online either way). Like, my main concern is whether it will slow down my computer or not. Which macOS can I upgrade to that won't slow down my computer?

Edit: I was thinking of doing Sequoia, but I need to know if it will slow down my computer or not.
