Sometimes the reissues turn out better then an original release. However today I no longer buy re-issued anything, If I have to own it I hunt down an original release , it may have noisy surfaces but at lease the music is a live.
I think the only company you mention that accually did a good job at re-issues was Classic. A couple of examples of poor re-issues was particularly from Speakers Corner and Mobile Fidelity. Speakers Corner with their Mercury Living Presence and decades before Mobile Fidelity with their entire catalogue, a myth has carried on over the decades about their re-issues very few are accually good.
Don't rely on positive chat over the net or favorable reviews ,find the 1 or 2 % that don't like it and put your faith in what they have to say.
