I like the vintage ones, particularly material from tougher to find HOF players because of their relative scarcity (the majority of whose memorabillia is intact, tightly held privately, and not nearly as unique as is made out). I wouldn't collect a ton of the modern stuff because then they do tend to take on that cheap dime a dozen feel...
I actually think they look pretty good, though much like all cards it comes down to the design and aesthetic abilities of the manufacturer. In the same way I'm a fan of some vintage issues, and others less so.....
I also find myself in the less likely to believe camp of the need for the big card companies to use faked memorabillia, when they can buy the authentic stuff for not so crazy prices at auction, AND not run the risk of being found out with the subsequent death of credibility in an industry that struggles to create much confidence.
Anyways....here's a couple of mine framed up
