recommendations for best 4 player maps?

So I downloaded the “most bookmarked” map variants from Halo 5’s file browser.
But are there any I’m missing out on instead of wading through pages hoping to find some gems?
Looking for 2v2 or 4 player FFA maps, slayer only. no swat, snipers, breakout, etc.

Thanks!

I have a few maps that technical my aren’t 4vs4 but could be if you like big maps. My forerunner refinery would be my smallest map if you would like to check it out. Though I recommend my verdant overgrowth map if you like infected maps.
