I like sonics the best, very nice use of layering and blendging techniques, although his font could be better. The Rei gives a more artistic feel.
Tepus's one is simple enough but has a nice feel to it.
FM's is just a background, so i won't go there.
Suicidals one is good, but the thing that makes it bad is the Rei picture itself, everything else is fine.
Now depsite Numerous praises i actually don't really like HSU's. The fonts are very simplicit. The rei image is a nice feature but i can't see much done on the voerall sig. The lines are a nice touch, but can be performed if given time.
Overall Sonic's has the colour, layers and style tog et my vote.
