Great source and, although that Thread was created back in 2014, the list is up to date.

About games similar to Stake's I can't tell specifically, but comparing different casinos I have used in the past I realised that many share the same game providers, so you may find several sportsbooks similar to Stake after a quick search.

BTW, OP, why are you looking for alternatives? I'm just curious: if you like that platform, why look for a similar but different service at the same time?
