My experience has been the opposite... I have a set of '56 WFL's, and I found them to be more warm and full-sounding than my old set of Leedys (which I think were somewhere between '61-'63).
The draw to the Leedys, IMO, is all about the lugs. I mean, I love Ludwig Classics, but the deco Leedy lugs are some of the most beautiful pieces of drum hardware ever produced. Also, the push button FT leg mounts are a bit more reliable and easier to use than the clip n' spring FT leg mounts WFL used.
It seems like Leedy kits are selling between $1000-$1200, with $1200 being the high retail end of the spectrum. I paid $1200 for my 13/16/22/5.5x14 matching snare WFL kit last year. Depending on finish and overall condition, I'm not sure one is going to cost you much more than the other. It's probably going to be close to a push.
The deal is essentially this drum kit in similar finish/condition plus the matching 5x14 snare for $895. Is that reasonable for these drums?
Hell yes. If you don't grab that kit at that price, let me know and I'll buy it!
