I'm generally in all Nike but I have a few of those "Grand Slam" tops that are really nice and not branded at all.
I do agree that having all the opposing logos looks weird. And I generally won't buy Adidas stuff.
Fed is the most 'different' guy I've ever watched live. The dude was a cheat code unto himself. He knew where every ball was going and put them away effortlessly. No one else has ever looked like that, not even Djok-or-'dal.
