I've had both the M50's and the Senns, and I'm in the process of returning the M50's, as their mids leave a lot to be desired compared to the Sennheisers.
If you can, try and shop around. If there's a local musicstore, see if they let you try out different pairs and determine which one you find best. What sounds good is for everybody something personal. Some may find the 598's bass lacking and want something more tight sounding, whilst others think that the bass is great and the soundstage is fantastic. It all depends on the listener, really.
All the local music stores don't have a very good selection - one or two sets under $200, neither of which are good, and then the massive price jump to about $350+. Joy.
I've considered getting the 598's, and using them only in private environments, and using my current headphones (HD 418's) as my set for crowded environments, but I'd prefer one pair, over needing two individual ones, especially as I'm not very happy with the 418's. I guess, when it comes down to what is the very core of what I'm looking for - it'd be quality. If the sacrifice is that I'll have to avoid using them in crowded spaces, so be it - I can always buy a pair of in-ears later down the road if the need arises. Quality, more than anything else, is what needs to stand out. My library ranges from anywhere from The Beatles to Metallica, from Lady Gaga to A Day to Remember, Judas Priest to Skrillex - so I really need a pair of headphones that can best cater to that variety.

Post headband stretch, they were superbly comfy (and I'm a comfort whore who tends to hate pleather), isolated very well, and had solid bass without being severely bloated. Perhaps if they still sold the blue box version, I'd have a pair if they were $90 or so.
The thing about this is, I'm ordering off of Amazon, so incl. shipping, they'll come to about $190 ($160 + $30 express shipping), while the 598's will be about $200 total, so price-wise, they're on a level playing field. I'm just so very nervous that the sound quality of the M50's won't be up to par with that of the 598's - so much so that I'm nearly willing to sacrifice a lot of my usage environments for the sake of clarity.
