Before there were any 28mm lenses, there were 35mm lenses.
Before there were any good 28mm lenses, there were great 35mm lenses.
This, to some degree, IMO, explains the poll results here, thus far.
I came to photography when there were great 35's, great 28's, great 24's...you get the idea. Sky was the limit if you had the bucks. The buck, for me, stopped at 24mm (Canon FD f/2.8), but I was in heaven. Briefly had a faster 35mm companion (f/2.0), but the 24 got more use. Only when I switched to Nikon gear some years later did I get happy with a 35mm optic (and, at f/1.4, why not?) but I eventually got another 24 for that setup as well, and the 35 got progressively less use.
Last SLR system I had found me with 20mm f/2.8 and 28-70mm f.2.8 optics on the wide end; the zoom got the lion's share of use, and most of that at 28mm, which I became quite fond of, but I wasn't fond of the thing's weight (but that lens, a Minolta AF "G", might've been the best damn zoom lens I ever owned, hands-down). This helped inform my next move, away from SLRs and back to rangefinders. When I got my first Hexar RF, the only M-Hexanon lens in the entire store was a lone 28mm f/2.8. I was hoping for a 50 for starters (and to save a few bucks), but bit the bullet and got the 28. Awfully glad I did – it's the most-used lens of the trio (the 50 f/2 and 90 2.8 rounding out the set), and I find it highly versatile, but at the same time it's not too hard to be careless with it, which might also explain some people's preference for 35mm, which is a bit more forgiving in some circumstances.
That lens, along with the rest of the Hexar rig, got a workout last night doing a photo shoot at a benefit event honoring Eli Wallach and Anne Jackson (words and pictures to follow; BTW, Wallach's favorite focal length to shoot with is 60mm...we had a most interesting series of conversations). A 35 wouldn't have come in quite as handy, while anything wider would have been occasionally unweildy.
So for me, in terms of general use, 28 is the Good, anything wider is the Bad, and 35 is...okay, anything but Ugly, but it doesn't quite do it for me (and this was a cheap analogy that I couldn't help using, okay?). 😉
