Best pair of gloves for sparring?

In your opinion whats the best brand of glove to use for sparring and why?

I am looking at Windy 16oz gloves and the TKO 12oz olympic gloves

I am not overly familiar with either brand. But I do know I wouldnt particularly care to spar with someone wearing 12 oz gloves. Unless they didnt mind me just hitting them alot and not letting them work. IMO 12 oz a tad light for sparring, unless you are a buck fifty or less.
