Myst is one of my favorite games, but I never could get into realMyst. The idea was great at the time, but I thought the visual fidelity was lower (despite being ... "real"), and the click-based movement never played well.

I did like Real Myst: Masterpiece Edition a lot (though it ran terribly on my powerful-at-the-time system). But I'd argue for the OP to play Myst: Masterpiece Edition first. IMO the interface is just as important to Myst as everything else.
