I also use Kreinik, both braid and blending filaments and haven't had any problems with either. I tend to prefer the blending filament with regular floss to the braid because I like the subtle bling it has (which rarely shows up in a photo, unfortunately). I've also used Rainbow Gallery's Treasure Braid and have liked it also. I steer clear of DMC metalics as I think they are not the best to stitch with.
