I remember the E-MAN Charleton issues (1974-1975) and the later 1983 series from First Comics. I'm not a fan of Joe Staton's art for DC, but I think his work on the Charleton E-MAN series was among his best work.
I'm especially fond of John Byrne's Rog 2000 backup series (his first pro work?), in E-MAN issues 6,7, 9 and 10, later collected with some other earlier CPL fanzine material in Pacific Comics' 1982 one-shot ROG 2000 magazine size b&w reprint. With a really nice wraparound cover by Byrne.
Here's Byrne's beautiful 1982 cover for the Pacific reprint collection:
And for anyone unfamiliar with Rog 2000, here's a site that affectionately displays just about every story and pin-up of Rog 2000 in chronological order:
