I'd keep the tak bayonet, the others aren't interesting or significant enough to give up for the performance. People talk about flare but honestly if you need a lens for such demanding situations get the Samyang and save yourself some headache. If you want Tak Bayonet performance for a bit more money get the Pentax-A 135 f2.8 since it matches the tak bayonet in sharpness while having the coatings.

The screw mount takumar is optical the best of the three on 'full frame', the lower edge performace of the M goes unnoticed on apc-c, build quality of the screw mount is the best, the bayonet takumar the worst (mine keeps getting grease on the aperture blades, even after several cleanings).

I'm surprised no one mentioned the SMC Pentax 135mm f/2.5 lens.
I am suprised, too. You can find the 135/3.5 on every fleamarket for cameras and it is bad! The 135/2.5 is more seldom, but MUCH better. I use it often on my K1 and I think it is in the same class than the 85/1.8.

You should buy one if you find it in good condition.

Individual lens variation would more than make up the IQ difference between these three. You need to do a test comparison on your three.
My M135 3.5 is easily the worst and my Tak Bayonet 135 2.5 is the best.
Obviously the 2.5 is a more versatile lens if you wish to utilise it wide open.
I don't notice any significant difference in the coatings.
