The 1.8, 1.5 and 1.4 are definitely better value for your dollar, given that the 1.2 can go for $500 and up these days.
The 1.2 I had came on a Leica M3 (with a Leitz screw-to-M adapter). I used it with T-Max 3200 for existing light, stuff like a band playing in a dimly lit bar for example.
I traded the lens even for a Contax II with a collapsible Sonnar (f:2, uncoated) and got pictures I liked much better under the same conditions with the same film.
