Finally! A good question! I would suggest that you stay with the more traditional ones and grind through them. They are refreshing given the state of gaming, and particularly "roguelikes" nowadays.
Start with the original rogue, you'll find a free, tiled, and more accessible version here:

Then I'd say give Angband a shot. It's more about delving and adventuring for a bit, then returning to the town to rest/recover. Keep doing this until you're godlike and can defeat the baddie at the bottom of the dungeon:

Then give Dungeon Crawl Stone Soup a shot. This one's more about exploring a vast dungeon to find orbs. Maybe the most accessible:

And lastly, you can't go wrong with Nethack, although it's more about following a process. If you do the right thing at the right time in the right way, you won't be filtered.

A lot of the haters here are right. Hipster "roguelikes" and "roguelites" have created a whole generation of indie proc-gen slop that can't die soon enough. But these old-school neckbeard games from the before time are pure SOVL.
A good hint, if you have to pay for it like a normal game, it's probably shit.
