Best modern rapper?

Music now, who's your favourite modern rapper? 50 Cent, Eminem, whatever.

Ice-T, he raps on his u-stream.

Paul Wall 

MF DOOM, maybe the best ever!

I wouldn't define 50 Cent or Eminem as 'modern'.
 
Define 'modern'.  If we're talking about a rapper that still puts out new records?  Kanye West or Jay-Z.
 
New, less than a few years old-ish rapper? J. Cole.
 
Best of all time?  The Notorious B.I.G.

drizzy drake rogers I'm too busy to play father and when it comes to the game I'm willing to play harder

Common's pretty good.

Lupe Fiasco

I think Snow is still putting out records. Anyways he gets my vote.

Eminem and his freestyles

I don't really listen to rap music, but I figure that Eminem is one of the best rappers in recent memory and certainly one of the more unique artist in mainstream history that doesn't rap about the usual things in rap music (money, cars, TVs, whores, that kind of stuff). 
 
He still does produce music. 
 
Though Ice-T and Jeff gets honourable mention for being awesome.

Eminem fo show. And this is the perfect opportunity to post an awesome montage without being criticized for spam:  

" Lupe Fiasco "

" MF DOOM, maybe the best ever! "

I'd like to add my name to the Lupe Fiasco list.

Jeff Gerstmann

Immortal Technique

Do you like Food & Liquor or The Cool better? "

Right now I think I have to go with Kid Cudi.

Kanye. And pretty much however Damon Albarn puts on the Gorillaz records.

Lupe Fiasco without a doubt. There are underground rappers that keep my attention like Pete Philly and MF Doom, but whether underground or mainstream, skill is skill. Two albums in and Lupe has yet to disappoint me.

Raw flow? Doom.
Writing? Pusha T.

Shad, DOOM, Aesop Rock, Slug (Atmosphere). 
 
  

Kanye West

I hate Rap so I guess Weird Al because that man can sing any kind of music and make it amazing.

Best rapper is kind of like pregnant virgin.
 
It don't make no sense.

  
  You don't see many rap ensembles any more. That's why I like Flipsyde:
 
 

Nas, no doubt, but with Lupe Fiasco pretty close to him and Eminem on third place if I had to make a top three. Food & Liquor is in my opinion tied with Illmatic as the best rap/Hip-Hop album of all time.

Aceyalone, Gift of Gab,  Abstract Rude, Mikah 9, MF Doom,  Dälek 

" Jeff Gerstmann "

Who asks more questions, Alex Trebek or bearcat?

 Actually, a friend once told me, "Music is like candy. You have to get rid of the rappers." Unless it's Jeff. "

Why Soulja Boy of course, you see he has the anime swag.

Lol ,  I like how eminem is the de facto answer for everyone who say they don't listen to hip hop 

Anyway , my vote goes to andre 3000. He truly is a modern day poet

Tech N9ne, easily

" Shad, DOOM, Aesop Rock, Slug (Atmosphere).

Drake,B.O.B, and some other

SHAD is great, Drake has his moments, and I love me some Weezy mixtapes -- albums are always shit.  
 
Lately I've been listening to EARL and Tyler The Creator from ODDFUTURE, after a friend recommended them to me. Nasty and pretty crazy lyrics about rape and crazy shit, but some of their lines are crazy, crazy good. Recommended to everyone who likes hiphop, superhardcore old school dudes that hate pretty much everything that isn't samplebased beware though, as the beats are pretty modern and electronic. EARL is like 16 and Tyler is 18 or something, so they have crazy potential to say the least, if they can stop being absolutely insane and survive til their 25th:  http://vimeo.com/12056212 (BEWARE, extremely nfsw and generally upsetting, even though it's probably not real. Looks fucking real though.)
 
Otherwise the best modern rapper is Big Boi, in terms of flow and lyrical content. Unstoppable.
