Using 11s at the moment, both on 24 3/4", 25" and 25 1/2" scaled guitars, but I don't think I would use the words "better" or "worse" to describe the difference in sound quality between different gauges. I'm actually considering going down to 9s on my strats again, as there is a certain twangy quality that I like with strats strung with 9s, especially on gain tones, low through high. At the moment, the heavier gauge make me play different, but I can't say that I sound objectively better. Just different, as a sum of the tone of the strings and the way you play when you approach different gauges.
