Jarren Benton (Specifically Skitzo, Razorblades and Steak Knives, Cadillacs and Chevy's, and Go Off) and Brotha Lynch Hung are good if you like horrorcore.
SwizZz (Crank, Zoom In, MartianzZz Vs. GoblinzZz) and Hopsin are pretty on point right now, but Hop seems like he wants to quit. Which is weird because he just started buzzing.
Chamillionaire is a lot about money and cars, but Sound of Revenge and back are still pretty cool. He's pretty deep now, one of his recent releases, End of The Knife has a sweet perspective.
Like someone else said, Luda will rarely disappoint, and T.I. Vs. T.I.P. is a good album, and Troubleman seems like you could enjoy that even better based on your personal tastes.
Killa Kyleon has gotten pretty good over the years, another H-Town heavyweight. Who Shot Ya and Time Machine freestyle will either make him or break him for you.
And while I'm personally having trouble listening to Tech N9ne right now, he's a must listen. All 6's and 7's is a great album, even if He's a Mental Giant makes no sense at some points.
Lynch's Manibalector album is grim, gruesome, and disturbing, but if that doesn't bug you, it's fantastic all the way through.
Oh, and I also mess around, focusing on clowning around, and sticking as many rhymes and double/triple entandres into one verse, we really can't advertise our own stuff, but we can have our Youtube links in our profile. You can check it out, but I'm not sure how to tell you without getting a warning. But I suppose I just did.
