Crankcase breather catch cans

I haven’t bought a can yet, trying to get thoughts on which is the better manufacturer. They seem to be all over the place as far as price. 20.00 Amazon to 400.00 +/- race cans.
Makes sense that the baffled ones are more efficient.

I’ve been looking at the vacuum pump / separators also. Pricey and not sure if it would be better to stay with pcv valve.

I like the idea of keeping the combustion as clean as possible.

I forgot the make of the covers but they are a fairly well known brand.
The builder has them and I’ll get him to check.
Thanks again
