The "topcat" brand are the good ones... Nicks is one source for them...There's a big variance in the quality on those as you've found out... ...The window rattle is a bit tougher...First take the easy way out and look for any loose/misadjusted parts that would eliminate the rattle...From there check all the plastic wearing parts that can be replaced {track guides etc...} and lastely the regulator hinge points will wear and create rattles....
