Neither, I have a big mish-mash of alsorts of gloves and pads that ive found and thought look good. I think most of my gear is actually Blitz...mmmm...
I have more ringside stuff than anything. I have a pair of 14 oz. everlast gloves. I never use them unless we are sparring outside of class because my coach won't allow us to use anything less than 16 oz gloves in class. I also have an everlast portable ring timer that I absolutely love. I use it more than my ringside timer. On the other hand I have a pair of 16 oz. ringside gloves I use all the time, a pair of ringside focus mitts, a nicer plug in ringside timer I never use. I also get my wraps from ringside.
I think Everlast tends to hold up better than Century. I've had a heavy bag by Everlast for years now and it's held up great.
