I totally agree that you can't go wrong with either. To me, metal v.s. wood is strictly a personal choice with no right or wrong involved.
Price, condition, original components, etc. obviously might play a part in your choice based on whether you're looking for something collectible or for a "player." These factors may also prove to be important if you're considering re-sale value sometime down the road.
Personally, I love the "woody" sound for 60s music but others might differ. I'd suggest that you try out both drums (if possible) to see which sound you prefer for the type of music you're going to be playing.
A Ludwig WMP Super Classic snare would also fit in nicely with your kit. Just a thought.
Have fun!Keep on Pl
