If you've already tried each one and still can't decide, I suggest flipping a coin!
Assuming image quality is comparable, I could make an argument for each one:
S-M-C Takumar . . . Killer looks and build. Wins on coolness factor.
Takumar Bayonet . . . Best low light speed and shortest minimum focus distance (1.2m vs 1.5). Has a (too short) built in hood.
Closer focusing is a great convenience for me, but my Tak Bay copy is soft at f/2.5, has poor flare resistance and has low contrast at
all apertures.
SMC M . . . Smallest and lightest. Also has a (short) built in hood. I'd think this would be the natural choice for a mirrorless camera simply due to its size.
It would be my choice.
Good luck choosing!
