UCP is a pretty junky pattern for most terrain... there is a reason it was replaced. The fact that it was even put into service is appalling.

marpat is ridiculously good... especially in the fall. multicam works well unless you have mostly green, then there's not enough green in MC. It works where there's lots of sunlight and golden tones, it works decent in heavy woods.

ATACS FG and AU are nice patterns too.

A lot of the multi use patterns are confusing though, they look both green and tan so some game organizers want to limit their use due to players not being able to identify teammates vs opfor.
