From I read, the Macro versions of most 50s although slow tend to the sharpest of 50s. I have a Sigma 50mm 2.8 Macro it is tack sharp. I got after I did my testing, but I would rate it up with any other normal lens I have. In terms of M42, unless going back the 50s or 40s it is hard to find a poor lens.

Any macro lens is going to be "tack sharp" in the magnification range it is designed for -- i.e., very close-up. Outside of that range, it's resolution will be less than spectacular. So don't wet your pants. Macros can be used for "distance" photography, but it probably won't be what you expect. This is exactly like using a normal 50mm lens for macro work. You can do it, but the results won't be as good as with a lens designed for macro magnification.

Just to be sure, my test target was an arrangement of 4 high of 11"X17" tabloid prints so clearly not macro. It may not be the ideal use of this lens but still very good.

Can't seem to find the listing - but I'm in the UK. They do pop up from time to time though, I might try getting one.

Mine is a Super-Takumar version with yellowed thorium glass. Haven't shot it for a while though, need to rectify that.

That's an impressive demonstration! Well, "especially if shooting film" wasn't so much my own opinion as what's often said, but in my case it seems largely to be true -- I mostly shoot expired film which is visibly grainy. And the scanner I'm using isn't the most advanced either.

With expired film (unless it's been miraculously well preserved, which happens sometimes), I guess it makes even less practical sense to look for the very best lens, but still why not.

Same thing happened to mine while sitting in the box. A few weeks sitting in the window frame during summer made it as good as new.

I don't mind the yellowing that much, and I'd rather not risk putting it out in the sun, as it can produce oil condensate on the glass (happened to a Chinon lens). A uv lamp could do the trick, but I don't have one.

You can expose a yellowed lens to natural UV light without baking it in direct sunlight. Let's not be ridiculous. I have a Minolta Rokkor 58mm f1.2 without any yellowing.

First, depending on how yellow the lens is, it might not be an issue at all -- in terms of photographic results. Some people will try to make a big deal about it suggesting, for example, that yellowing will mess up your exposures. If you are using a TTL meter, it won't -- even if it is severe. And if you are shooting B&W, yellowing will probably help your results -- no matter how much yellowing there is.

In addition, you don't need a north-facing window to solve the "problem". Any window will work, but you don't want the lens in a hot window that gets direct sunlight on the lens.

Depending on how much yellowing there is, it might take a while for it to "resolve".

Some people even seem to keep it on purpose, because of the golden glow it can impart. To be honest, I don't really see any impact, not last because I tend to shoot expired film which often already has significant colour shifts. I also have a Pancolar that's got more yellowing, but I haven't shot with it enough to see how it affects the result.

I find no reason for why not nor would I look for one!

What is the best fast fifty (-ish) lens in m42? ...

The Carl Zeiss 50mm f1.8 Ultron is a candidate. You did not say cheapest, right? (watch out for bayonet mount models that only work with the Zeiss Icarex 35S and related cameras).
