If you want to hear for yourself, get this Blu Ray Music / SACD 2 disc set. The Blu Ray has 96/24 and a 192/24 PCM track, and the SACD has 2 channel and MCH of the exact same source material. You can do your own shootout. In slightly prefer the SACD, but this could very well be placebo effect, and I'm not sure I could tell the difference in blind shootout. The first track is also downloadable as high rez flac, so you can even do a three way shootout.

I am personally not too hung up on resolution anymore. Recording quality trumps resolution any day of the week in my experience. I can happily live with a well recorded recording in 44/16.
A much bigger regret is the lack of MCH content. Native MCH really takes things to a different level for me, but sadly MCH is all but dead except for classical SACD, and the odd good concert BR.
I only spin MCH SACD - some classical, some jazz.
