Really you picked those two, what about nikkas like Swave Sevah, charlie clips, hollow da don, shyt I even think xfactor could possibly give him fits.
The reason i said Ill is because everybody know's Ill is mr. 2nd round when it comes to this battle shyt, that's when he really turns up the pressure....he's a problem for anybody when it comes to that, he can get busy in the 3rd to.
The reason i chose Big T is simply for a battle of complexity.....no need to explain that if you know lux and t, you know they both love havin' complex bars.
Now on to your suggestions:
x-factor yes......because he's the only consistent veteran that's battling these young boys and still able talk that shyt, ma' memory slipped on x, so yeah he's one of the only two that could possibly give it to lux besides mook. i was mainly talkin' about the NEW breed.
Swave Sevah is hot ass crack.....he's like a math hoffa with glasses and ok lines....he wouldn't last the 2nd round
Charlie.....meh he not there yet......he's still hit and miss.....the only people he flat out beat is X-factor (not because he rapped for 21 minutes, he had 21 minutes of versatility it's a few things i could pinpoint but i'm not.....& Tay Rock. Both his bars and performance against Verb was over hyped at SM 1 though, and he wasn't that impressive against Big T. He's decent at best, i will say he's had a moment or two here and there.
Hollow.....i take everything i said back.......hollow would get trashed half way through the 2nd round.....i had to remember this the same hollow that battled in grindtime where it's mostly jokes over real bars.....when he was on his smack shyt he trashed big t i'll give him that, did ok with goodz, and didn't do too much against holla that had me like oh sh!t....ain't this same n!gga that got trashed by ars with a recycled verse on fight klub??.....smh stop it b. Y'all got him on a pedestal as THAT dude in url when he's just ok on his best day, if we talkin' bars.
