I've never heard them say "we remastered the material, but it doesn't really sound particularly different/better than what's been out before", even though I would argue that's the case often enough. This is an easy pass for me, as were the Mobley and Morgan. $ and shelf space are not limitless, and I have everything except the three new alternates on CD already (also have all the Mobley and Morgan material on CD), and they have the (subjective, for me) magic of the Blue Note artwork, which the Mosaics never do.
