As you all know here, a 45 rpm recording the groove spacing is wider spaced which puts less stress on the cartridge giving a overall relaxed presentation.
Classic Records did a "absolutely spectacular" job with Harry Belafonti's 1959 Carnigie Hall concert re-issue on single side 45 rpm box set.
Many of Music Matters Blue Note 45 rpm re-issues are another contender for top re-issues on the Planet.
Would a single side release of these Blue Notes exceed the dual side's ?
I like the single side release and wish all my 45 rpm's were done this way, for cleaning and playing.
