Best reverb or effects unit to compliment the Moog Subsequent 37?

I'm currently using the NTS-1(2) with a few extra custom reverbs downloaded onto it, but I'm really ignorant about dedicated effects units (never played a guitar or stepped on a pedal in my life) and I'm not sure what to look for that would best compliment the Subsequent 37. Budget is around ~$200, but could be stretched if y'all have something you'd love to recommend.

In short: Best/favorite effects and reverb units to compliment the Subsequent 37?
