In my opinion, it depends on the manufacturer. I was talking with a metallurgist who is also a motorhead and he explained it to me like this: Making a good hypereutectic alloy is like balancing two pins on the sharp ends. If you are good at it you can do it and make a great piston. If you are trying to cut costs (read: cheaper pistons) you can really screw it up and that leads to a weaker piston.
Sealed Power seems like a good brand. I've never run their stuff but from stuff I've read on other forums there aren't too many bad reviews. KB Silv-O-Lites on the other hand can be hit or miss. I've got one of those sitting on my desk- it came out of a 427 BB and didn't get the job done. The KBs also need a really tight ring gap from what I remember; kind of out of the ordinary.
