Those Winnetou films don't really look all that appealing.
I think "Hate Thy Neighbor" just might be Baldi's best. I find it much more re-wacthable than "Texas adios" or that snoozefest "The Forgotten pistolero" (Have to give this a proper 2nd viewing). And I think the plot holds up better (and the action is much more consistant)than "Blindman" or "Get Mean".
I made a mistake with Horst Frank who in fact starred in Winnetou:Last Of The Renegades

Blindman has to be the most original and best Baldi sw,followed by Viva Django,Forgotten Pistolero,Texas Adios and then Hate Thy Neighbour.
I only watched about 10 minutes of Get Mean which i absolutely hated and unfortunately Coming At Ya is unwatchable but this may be due to the wrong 3d glasses.
I'd be interested in catching either of the Carambola(Trinity rip offs) films and i'm sure Horst Frank is involved in one of these too.Not sure i'll ever try and get hold of Rita Of The West!
