Hi, I'm finishing up refurbing A Dell 9010 & 9020 Mt for editing and audio. i5 & i7

I've been using win 7 pro for more than a decade and I really enjoy it.
Begrudgingly coming to win 10 late, because early issues which seem to have been resolved.
I know I should use win 10 exclusively but if I'm doing just Audio Video and Graphics, One has win 10 one has win 7
Will I see any performance benefits in 10 that 7 would not do? Rendering, hardware conflicts, old drivers to use with firewire mixers?
I wish 10 looked more like 7?
just want to hear what others are doing.
Thanks.
