Who are some 80s Lyricists That Could Rhyme Their Asses Off?

I really like Rakim, D.O.C. and G Rap. KRS isn't as technical but his energy and presence is incredible. 80s had some awesome albums and songs, but it isn't as easy to find MCs with rapid fire flows, punchlines, tongue twisters, clever flow, metaphors, etc. I want to see if I'm missing anybody (Kane is hit or miss for me)
