My only experience is with L&L Broadway Standards. I own a 5.5x14 and 6.5x14.
I've been playing the 5.5 for the last week. Every time I put it on the stand, I think it's as fine as any snare in my collection, including 2 high-end Sonors and 3 RKs. I actually prefer the L&L to my RKs.
Incidentally, I'm looking to sell the 6.5. In case anyone reading this thread is interested, please pm me. It's about as close to mint as a 60 year old drum could be.
