Vintage Gibson ('54 in my case), ReWind, ECP and then a distant 4th Gibson Custom Shop from a Wildwood spec 330 that has supposedly lower wind P90s. The Custom Shop are actually the only set of new Gibson pickups I've ever liked, they just lacked some of the definition that the other winders have.
My ReWind and ECP's are both based on the early 50's P90s and are very clear and articulate like a good single coil, fantastic for cleans and just absolutely rip when distorted. You really can't go wrong with either brand IMO, James (@cooljuk) is a totally class act so I wholeheartedly recommend you listen to his youtube demos and strike up a conversation with him about what you're looking for.
The vintage set I have are phenomenal, any doubts I had about the mystical powers of vintage wire were squashed as soon as I plugged into this set. Absolutely never leaving this guitar or my ownership...
Early '52-53 Gibson p90 and '56 (my Les Paul Junior) if we're talking vintage.
If it's modern, Rewind Electric is the way to go. You'll be saving a lot of coin and be grinning as soon as you strum that first chord. I don't think I'll be buying vintage p90s unless it's for a restoration. I don't feel the need to since James winds a killer p90.
