In terms of Unique Brandable names IMO 'erotistic' and 'erotistica' are your best for branding. However unique brandable names are more suitable for the end-user rather than a reseller, so these are difficult to give an accurate value to. If you can find an end-user i would expect you to sell these in the low-mid xxx.
The other ones unfortunately i would value at reg fee to low xx - reseller. They don't focus on the large industries where you can get away with numerous domain variations due to the market size, these are more targeted towards niche markets.
For example some of them are 3 words long, including one 'descriptive word' which allows for many variants to still be available at reg cost.
I recommend developing erotistic and erotistica and once you have some traffic, this will raise the value.
Also rtgd.net - mid XX for now.
Cheers.
