need advice on best CD versions of these

Hi. Can anyone give me info on what CD is the best version of:

Bob Marley - Catch A Fire
Has anyone compared the MFSL version with the standard Tuff Gong CD? I wish the Tuff Gong CD would say the date so I could get an idea.

Cream - all albums
I have the Those Were the Days box set w/new remasters. How do they compare to the DCC and MFSL gold CDs?

Santana - Abraxas and Santana(1st)
new 1998 24 bit remasters or older MFSL/DCC versions?

Thanks in advance.
