Well - Hill's been a mixed bag of reaction for me. I really like his Michael Cray, but (I know a lot of folk liked it) Black Lightning/Hong Kong Phooey just didn't work for me (part of that is undoubtedly that Denys Cowan is a hard sell for me - usually I need a writer I already know and trust like Priest to make me work with Cowyn's style). It just felt like the problems in that one were overcome with a bit too much handwaving, and the characters didn't feel that distinct. But, also to be fair, I don't know HKP at all, and Black Lightning only through Year One.
So if he's got a great Tec arc, I'd be all for him as the ongoing writer (especially since DC seems to be dragging its feet on Outsiders for no apparent reason). He's definitely one of the best writers in terms of fan interaction I've seen in a long time.
