I'm slightly ambivalent about level scaling: vanilla Oblivion was a good example of it done wrong, and even though I enjoyed my first play-through, it soon became a case of "seriously, what's the point?" as essentially the same old enemies and equipment were simply replaced visually, pretty much.
But then again, the assorted overhauls really showed the potential of Oblivion's engine by using much more fine-grained scaling: FCOM (a compilation of Oscuro's Overhaul, Martigen's Monster Mod, Fran's and other major overhauls) showed just how good it could be if done right. My personal opinion is that carefully considered level scaling is better than totally fixed levels. But I suspect it can be hard to get it right; then again, it's also hard to get fixed levels right, as the amount of discontent about Cyseal's environs shows.
I don't know what The Answer is, if there is one. Probably just to accept each game on its merits unless we feel like changing it. Which I'm not saying in any sort of finger-wagging way considering I'm as likely to complain about stuff as anyone else. And frequently do so.
