which cassette?

Now I know this question has probably been asked many times before but I’m sure each rider has a different circumstances so ill ask anyway. I have a shimano sg 52/39 front crank/cogs, 8 speed on the back and in my little group I’m the stronger climber, but what cassette would benefit me more for the hills as they have a compact cranks and can spin the legs up the climb where as I have to grind to get there.

If you need more details I’ll try to help as much as I can. I have looked around but all the options/variations are quite overwhelming.

Thanks in advance
