I used to own the ESW9, ESW10, ES10, P5, SRH840, T50p, and I've practically owned the HD-25 as well (well, technically, they weren't mine but...). I recently received a pair of DT 1350. Sorry, we're gonna talk of the latter quite a lot in that post, but there's a reason for that.
All of them are interesting alternatives to the HD-25. The latter seems to be recommended all the time on these forums and I guess there's a reason why : they're cheap, well built and sound at least OK with most genres and good with others.
You seem to listen to rock first and then other genres second.
The HD-25 are then a really good choice. Actually they're probably the best of the ones I tried for those genres as long as we're not talking about VERY well recorded rock.
But IMHO they're not very well suited to other genres. The question is therefore how much do you stray away rock and for what genres, and which headphones will give you a stronger performance with those genres than the HD-25 while retaining its qualities with rock.
So we can already dump a few of them which just don't work IMHO for rock : ESW9, P5, and to a lesser extent SRH840, and to an even lesser extent the T50p (that one would be dumped IMHO if it weren't for its class-leading speed).
The ESW10, ES10, DT 1350 are all good with rock. For dirty rock (Nirvana, punk, etc.), I still prefer the HD-25 to the ESW10 and ES10, but not to the DT 1350. The latter might not have the drive and fun factor of the HD-25, at least unamped (amped, that's another story), but they're much less tiring to listen to and that's a plus point for those genres that often display harsh trebles. I find them equal in that regard. However, for well recorded rock then I'd choose the DT 1350 over the HD-25 most of the time. Reason explained later below.
If you want to listen to jazz (Norah Jones it seems), then the ESW10 and DT 1350 are much more better than the HD-25. The latter is just dry and just doesn't convey the sense of ambiance / soul well. The ESW10 has fantastic female vocals, the DT 1350 is more balanced and doesn't do anything wrong. As the recording quality increases, I prefer the DT 1350 over the ESW10.
If you want to listen to electro, then the ES10 is IMHO better than the HD-25 because of its more rounded and fatter bass. For more experimental / well recorded electro the DT 1350 is IMHO the best.
For classical music, well it's very simple. The HD-25, ESW10, ES10 are all inferior to the DT 1350 by a light year shot.
In fact you seem to see a pattern : the ESW10, ES10, and DT 1350 are usually better at other genres than the HD-25, and as recording quality increases I prefer more and more the DT 1350 to the others in pretty much all genres.
That's because IMHO the DT 1350 is actually a slight technical leap above the others. While I think the HD-25, ESW10 and ES10 are technically on par (if you graded their technical abilities such as bass extension or soundstage and averaged them they'd be IMHO in the same category), the DT 1350 is superior to them. It is not a night and day difference and I don't think it is that noticeable with average recordings (75 % of what's around here). But as recording quality increases, I think they pull ahead and show their technical abilities well.
So to sum it up :
HD-25 is IMHO the best for rock. If you have a large proportion of well-recorded rock, the DT 1350 takes over.
The ESW10 and DT 1350 are better than the HD-25 for jazz and acoustic, while still good for rock. If you listen to a large minority of jazz / acoustic it can be interesting to pick them over the HD-25 (which I really dislike with that genre). As recording quality increases the DT 1350 takes over.
I prefer the ES10 to the HD-25 for electronic music, except for very high quality recordings or experimental / ambient electronica where the DT 1350 is in my opinion a better value.
For classical music it is very easy, the DT 1350 trumps them all by a long shot.
For world music, DT 1350 and ESW10.
BUT as you said you don't listen to electronic and only occasionally to jazzy / acoustic stuff, so the HD-25 remains one of your best bets. The DT 1350 will be even better, but only if you have a decent portion of your rock interests well-recorded and accoustic rock and pop constitute a big minority of your listening time.
As you can see 25 years after their introduction they're still very competitive
