Tough to say in some respects since you don't have much data 'bout what ya ride in, or where you're located in your post.
In damp Seattle, I'm a fan of salmon pads, they are noticeably better in the rain. As far as squeal goes with a good fresh set of salmon's I've managed to keep avid shorties quiet; however you should clean your rim & check your pads. If the pads look dried out, don't bother fussing at the toe in, they'll still squeal. Just pick up some new pads & then play with the toe on them.
If you really wonder you can buy a set of both & try 'em. Not too expensive to do & that way ya find what you like, it may be that in warmer environments then 'round here the harder pads work better.
