If you ask me Durango is indeed by far the best. Some others are ok ( 5; 6; 17; 18; 24; 25). Depends on how hardened you are.
Bullets Don't Argue is a naive one, but not bad
May God Forgive You... But I Won't wasn't released yet, and will maybe not in the near future.
7 is only for Fidani fans and Arizona Colt Returns is a total turkey imo
3 bullets for Ringo is one many despise, but I had fun with it. Some scenes are pretty good.
