I haven't seen a recent (5+ yrs?) one. Most zones have been leveled out to within +/- 15% not including such things as dungeon modification (+15%). Kunark zones still have a slight negative modifier, as far as I now, but that doesn't necessarily make them horrible exp. High Hold Keep has been reduced substantially to basically equivalent to other 20s-30s zones, instead of it's once 150ish % bonus, and is why there is rarely anyone there any more, instead of being the it place for the 20s and 30s.
For pretty much all levels, I go where I can kill reds around 5-7 levels higher, if possible, at a fairly good rate. At higher levels, solo / molo that won't be possible, but generally you can find, if well equipped dark blues (within 5 levels) at any level to kill at a descent rate. the +/- 5 levels bonus is pretty significant, especially on the red end, but the kill rate has to be up there to make it worth while. Some zones are better than others, and from what I understand it is based alot on the difficulty of the zone in comparison to other of similar level.
A lot of people like BoT, probably because of the easy single pulls there, and the mobs seem fairly easy to me as well, but exp seems to coincide with it's ease. I always liked HoH and PoF alot better than BoT, and even GE for ealier levesl (<65). Hotzones have a variable but average around 25% exp bonus, which generally makes them ideal zones, if other factors don't hinder them (KT with horrid visibility, way too many HPs, and way too hard hitting for their cons being a prime example of a not worthwhile hotzone).
Anyway, zone experience modifiers are much more equivalent now than they were, and finding a good spot where you can maintain a high kill rate is probably more important than ZEMs now-a-days. Hotzones just make some otherwise not-so-great zones a good alternative, and those that are good on their own, great ones.
