when i think of best its mostly whos makin the most hit and most money and have skill
so
eminem (best lyrics tightest out right now)
50 (ton of hits own shoes pretty good lyrics)
ludacris (phat flow good movies hits good sales)
2pac(best lyricist of all time tells stories in his rhymes good sales movies)
chingy (relly big right now lyrics is ok )
lil john (lot of hits sellin lots of records)
nelly (lot of hits and sales)
jay z(lots of sales but way over rated)
ying yang (hit songs)
biggie (a good mc lots of sales couple of hits but doesnt compare to 2pac)
there u go theres my list of best mcs
they may not b the best lyrically
but they got fame and money
even if u got the phattest lyrics
it doesnt mean ur 1 of the best mcs
u could b #1 rapper and no1 would care if u werent famous and had lots of hits
thats just my opinion peace
