I agree with dr Jawa. I find 5.24 to be fairly well balanced, too. Noticeably better than 5.14.
Well, at least for me, the big thing was the word "amazingly".
I don't think any game fully backwards-compatible with 5.0 can be "amazingly" balanced. I think it's quite possible to improve the balance, and I completely agree that 5.5e did that. I believe I've even said as much on this forum, some time back--and got pushback from some folks here who claim that the designers don't care at all about balance.
I just see it as...well. A building that is one story tall is not "amazingly tall", I think we can agree on that. A building which is
two stories tall is, relatively speaking, significantly taller--double, perhaps more than double because of infrastructure differences. But I am fairly sure nobody would call a two-story building "amazingly tall".
Now, this is extreme for effect. 5.0 was, for example, significantly less broken than any version of 3rd edition ever was. So that would be more like the one-story building, and 5.0 would be perhaps a three- or four-story building. An eight-story building is, certainly, a tall building. It is not "amazingly tall". Even if every building in (say) a given reasonably-sized US state (like Nebraska or Colorado) is eight or fewer, that's not really a reason to call such buildings "amazingly tall" when there are other buildings in other places that have
several dozen floors, and the tallest buildings in the world are over 120 floors.
5.5e is better-balanced than 5.0. Anyone who disagrees with that is, in my opinion, being pretty silly. But "better-balanced than 5.0" is not a particularly high bar to clear, just as 5.0 being "better-balanced than 3rd edition" was in no way a difficult bar to clear, considering it's beneath the floor.
