Seriously, none of them. If you're pushed to choose, I'd say 7 with another font and without the 1998 effects on the name. Maybe the font without those effects would work as well
6 is the best but I'd never imagine that's for an adult site, so based on that it's the worse, go figure.
If you can, I'd extend the deadline and wait for more entries, ADC usually gives some great results. And wait for the last minute entries, the best ones usually are posted at the end since 99.99% of these so called designers copy everything at sight
