Theme sorter?

You mean redundancy sites.
ixquick, or google if you want all of your information shared with the federal government (and worse), is all the theme sorting one needs.

Who uses these redundant sites? Probably only users who are only window shopping.

If one is looking for premium WP themes, they should find the author's page and investigate from there. (Learn to search.)

Cloners foul the web for everyone. Don't patronize sorter sites/redundancy pages. Even affiliates shave well-earned profits from the plethora of great WP coders.
