I generally prefer to avoid doing things others already do, so I've often directed AT into niches no-one else covered, and thus don't really know much about alternatives unfortunately.
I've seem some aspects of what AT does appear over the years, like there have been sites offering DDLs, and there was someone who used to mirror a lot of stuff onto Usenet.
I once recall seeing a site which did screenshots of a lot of new torrents. Unfortunately I've never seen anyone attempt to extract mediainfo or subtitles (which is surprising given that it isn't hard to do).

But maybe others know better than I do.
