Just going to put out my personal experience. But I used Clevite for my KA-Turbo engine. No problems as of yet. Clevite Rod and Main bearings.. Matter of fact, I've always used Clevite. Even on my old V-8's.

I've heard ACL is pretty good. And you can get them 'Calico' coated with some sort of lube for initial break in.

But then again, OEM is pretty darned good.

from what I know Cosworth is at least a reputable name. Their products get used on race engines quite a bit. Shouldn't be any problems with these either.

Personally I prefer OE as Nissan has different grades for thickness of bearings. When you buy aftermarket, you rarely get to choose the picky thicknesses. However, that's all the thickness options Nissan gives you are. Picky. From what I've been told, the difference in thickness from thickest grade to thinnest grade is miniscule. I'm just OCD when it comes to motors, so I tend to try to stick as close to what the factory had in their.

Another thing to note about coated bearings is that as they see use, the coatings will wear off. When they do, the bearing does in essence become thinner, which can lead to problems down the road, but that's only if your bearing was already on the thin side to begin with. If you go for a tighter tollerance out of the gate, once the coating wears off, you shouldn't have any problem.

Are the OEM SR bearings F770?
