As you know it's all subjective, but I like many others happen to think that R2R is the ultimate format.
Copy and pasted below is a couple of paragraphs which help explain and I have also put a link onto the page it came from, it is a good read, It puts it across better than I can.
It helps to understand how vinyl and tape albums are manufactured. To make a record, the MT signal must be compressed to match the dynamic limits of vinyl. Some of the highs and lows are slashed in the bargain. All the other audio tricks needed to shoehorn a signal into those tiny grooves compromises the signal even more. Dubbing 1/4-inch tapes is a much simpler task. With no need to squeeze or tweak the original signal, it can be transferred from the MT relatively unscathed.
Then there’s the dicey issue of playback. With turntables, all sorts of mechanical foibles — rumble, skips, speed stability, inner groove distortion, et cetera — can further degrade the signal. In contrast, R2R is an exercise in simplicity. The only moving part at the point of signal retrieval is the tape, which travels in a straight line across a stationary playback head. Efficiency equals fidelity.
