The thing about Nethack is that it isn't so much a game as an elaborate joke. You don't win by being good, you win by memorizing all of the tricks. And it's only fun if you play on #nethack on irc.freenode.net, because then you can kibbitz with other players, they can watch your game, you can fall into addiction together, laugh about ridiculous situations involving cockatrices, etc. It gets boring after you win a couple of times, there isn't really much difference between the classes.
I thought DCSS was boring, 15 runes is way too much of a slog and that's with an easy class. If it wasn't so grindy I would like it a lot more, the skills are fun.
ADOM is similarly just way too long and you can't reasonably beat it without spoilers.
Brogue is perfection. You should try playing in the weekly random seed contests on the forum.
