With Killarmy, the highlight is the 4th Disciple's (w/ others) production and Killa Sin. 2 of their 3 albums (SWFQW & FL&W) are classics beatwise and DW is very damn good. Now, Killa Sin is the standout MC while the rest range between good, average, bad and godawfulwhythefukkisIslordallowedbymicrophones. So, I could see where the MCs might leave something to be desired but the beats alone make the albums so bumpable.
Sunz has 3 great MCs in KP, Razah & Prodigal Sunn. Early Prodigal can get lost in the mix w/ his more amped/yelling delivery, but by TLSBF, he smoothed out into a great flow/delivery. (And 60 Sec's only good when he's crooning.) While those 3 are all good spitters, some of the problems on that Sunz album was, with less KP involvement, they didn't know how to construct songs so you'd have nice verses over good beats but clunky, wordy hooks that didn't flow. Razah & Prodigal improved after that debut & have dropped dope solo projects but their lone revisit to the Sunz name suffered from weak production.
