Best "Hair Metal" Singer
But Rob Halford, Bruce Dickinson and Geoff Tate Blow these guys away by miles.
If not, out of the list, I'd go with Sebastian Bach.
I can't say I'm a fan of the genre but, (paradoxically?) without specifying the vocalists, I've noticed mention elsewhere of Britney Fox on the self-titled album and Cinderella's "Night Songs as being noteworthy.
The compilation album "This Is '80s Hair Metal" included the following which might provide food for thought:

I'm not sure that all tracks qualify (e.g. Di'anno singing "Wrathchild"!) but there might be a few names that pique the interest of those especially liking the style. It looks to me that the album includes re-recordings using some of the original band members. I've already cited Di'anno reprising his Iron Maiden hit.

Whitesnake was, at least until '86 or '87, a hard rock band in 70s mode, sort in the area between Aerosmith and Deep Purple. David Coverdale even sang with DP for a while.
But when their self-titled album came out in the mid-80s they surged in popularity with the hair metal crowd, opened for Motley Crue, and became an MTV-friendly band. Though stylistically, they were still riffing on 70s rock bands (namely Zeppelin) while adding some contemporary pop-metal elements into the mix.
