SACD VS Vinyl for Jazz and Classical

Well, I've been thinking of getting into vinyl for a while now but still haven't done it. I'm generally rather selective about my SACD purchases and only have about 25-30SACD recordings now although I plan to order a lot more as more and more reissues come out. I listen to mostly jazz and getting into classical a lot more. So before I buy any more SACD reissues of classic jazz and classical recordings, which seems to be available as new vinyl albeit at a much higher price, I was wondering if I should get into vinyl and purchase the vinyl versions instead if it's going to sound better and more like real music.

I know this topic has been discussed to death. But in my situation, where I have no LP collection but also not a substantial digital collection either, and the majority of my purchases will be reissues, will there be enough new vinyl available? Again, because of high costs I do tend to be selective. On another note, do LP version popular music such as Alicia Keys and Diana Krall sound better than its CD and SACD versions?
