I like my bronze, but I was going for a bronze build anyways.
Personally, for you, seeing how you are undecided. I would go with the black, giving you a neutral canvas to make it whatever color you want by bringing parts to Cerekote specialist as any color combo works with a black block. However, if you go bronze, you are limited to a particular colorway. I don't think a bronze block would look good with OD green or steel blue but would look great with a black block.
If you aren't going to make any color changes and want a little flair, the bronze is really nice in person, and I would recommend that route based on that concept.
I'm not an interior designer like my wife is, just a couple of cents from me.
