I like 1/72.
When I got back into modeling after college I began with 1/32. Great for detailing, but display and storage is a consideration. After a year or so I went to 1/72. Several considerations: Greater selection of subjects. Its fun to put a Sopwith Camel under the wing of a B-36, and the XF-85 does well there also. I like the visual perspective of having the Vimy, B-10, B-17, B-24, B-29 all the way to the B-52, Vulcan and B-2 on a long shelf. Same with fighter comparison. A T-bolt dwarfs an Me-109, and put an F-86 next to an F-22. You get the idea. Its also the "Time Line" of history spanning the Wright Brothers up to today. I find that particularly interesting. Display and storage is easier. I detail as much now as in the past (maybe more because I'm better at it) and the advent of resin conversion and phot-etched detail sets makes its easier. Yes the amount of extra detailing is limited when compared to larger scales, but 1/72 works for me.
