Should I stick to one cymbal brand?

Been playing for long enough that I'm starting to upgrade my cymbals, and I'm wondering if I should only use a single cymbal brand or use whatever I want. It seems a lot easier to just use 1 brand and maybe use 1 other cymbal from a different brand if I like it a lot. What should I do?

EDIT: I do have OCD, so aesthetics/matching are very important for me.
