A good R2R recording is the best analog sound you'll ever hear. But there are more reasons to have a reel recorder. One, they're fun to watch. Two, they're fun to play with. Three, the produce the best analog sound you'll ever hear (Yes, I'm repeating myself.)
I once, for a brief time, worked in a recording studio and was able to work with a number of 1970's decks: Ampex 440's; Scully 280's; Studers; JCI's etc. My favorite for tape handling was the Scully.
