Barney's list of Moore's contributions knocked me back a bit - I had no idea he was so prolific Way Back When, mainly remembering his second big residency in the 1200s; nor was I aware that he was responsible for one of my old faves Agent Rat. What a guy! I've also got quite a soft spot for Red Fang and Telguuth, but...
I've loved basically everything Kek-W has ever written for the prog, with the exception of Indigo Prime. From Canon Fodder II to Second City Blues (though maybe dodging Kid Cyborg), and his later renaissance with Deadworld and The Order, two of my all-time favourite strips, and some decent 3Rillers. I even quite liked Angel Zero!
So with nothing but respect for the depth of Steve Moore's contributions, I have to vote for man of the moment, Kek-W.
