I typically go with my '65 Ludwig Acrolite because it just sounds great in just about every situation I've used it in.
I own a new Gretsch Renown maple snare... and it's ehh.. ok.
I do like my Pearl Chad Smith Signature series snare. I've had it for 17 years and it's great for when you need cutting volume.. I use it when I play with the funk band sometimes and it sounds great!
I guess it all comes down to your ear and what you like, really. I've had a few vintage snares that I couldn't stand.. but I've got a couple that I'd tend to use before any modern one.
