Public Enemy sucks. Wu Tang has a pretty new one out called Iron Flag, it's decent. Some really good ones are:
50 Cent- Look Whos Back
Ali- Heavy Starch
Az- Aziatic
Camp Lo- Lets Do It Again (this one is OK, not cream of the crop but almost there)
B Rich - 80 Dimes
Cee-Lo- Lo And His Perfect Imperfections
Cormega- The True Meanin
E-40- Grit and Grind
E-Life- E=MC2(amazing cd)
Juvinile- 400 Degreez(classic cd)
Kurupt- Young Gotti Against The Grain(not pre-mo, but has some pretty good tracks)
Lil Wayne- SQ4(bunch of really good ones on this cd, he re-did a bunch of awesome but not insanely popular songs, some not remixed, just done over)
Nappy Roots- Watermelon Chicken & Gritz(insanely good cd)
Nas- Death Of Escobar
Outkast- Big Boi & Dre Present The Best Of Outkast
Snoop Doog- The Last Meal
Styles - A Gangster And A Gentleman(little hardcore at some points but there are some unforgettable tracks on this one)
Tha East Sidaz- Snoop Dogg Presents Tha Eastsidaz(lots of good ones on here, and who can forget G'd up?)
Timbaland & Magoo- Indecent Purposeal(This one is good but a little iffy, timbaland is really good at what he dose, cant say the same for magoo though)
Trick Daddy- Thug Holiday(a must have)
Wu Tang Clan- Iron Flag
X-Ecutioners- Built From Scratch(This one is presented by the Wu Tang Clan, it's more hip/hop than rap, more of the DJ beats type stuff)
There is alot of crap out there these day's, all the good stuff is more spread out among different artists now, you have to collect. How anyone could listen to the crap Puplic Enemy puts out is beyond me.
