Analogue Productions consistently made very good reissues. Same with Classic Records, King (Japanese) and Cisco (Japanese).
Mobile Fidelity is a bit mixed, but, many are very good. I particularly like a very early Mobile Fidelity reissue of Gordon Lightfoot's "Sundown."
When I am demonstrating what vinyl can do, I put on the following:
Ricki Lee Jones: "Girl at Her Volcano"-"Under the Boardwalk"
Clark Terry (Analogue Productions reissue)"Alternate Blues"-Alternate 1
Duke Ellington (original six-eye Columbia) "Blues in Orbit"--"Three J's Blues"
Great Jazz Trio "Direct from LA"--"Night in Tunisia"
Yamamoto Trio "Midnight Sugar"--"Midnight Sugar"
Amanda McBroom "Growing Up in Hollywood Town"--"The Rose"
Bill Berry "For Duke"--"Take the A Train"
Kraftwerk "Electric Cafe"--"Telephone Line"
Thomas Dolby "Aliens Ate My Buick"--"Pop Culture"
Little Feat "Waiting for Columbus"--"Willin"
Weavers "Reunion at Carnegie Hall -1963"--Guantanamera
