ok, i also acknowledge that you yourself acknowledge that there is a difference, but your emphasis is more on the playability rather than sound, and that is totally cool.
however, i would point out that in the video, the Edge said that 'they really sound different' when he referred to the bands using very heavy/thick gauge.
and yes i agree, and therefore put in my statement, that the bigger the difference in the gauge, the bigger the difference in sound.
between .09 and .10, the difference is not as big and probably is not genre defining, but i think playing the .10 will improve the tone if it is initially deemed to shrill and i'm sure some people would second my opinion on this.
as for the string vs pickup, i will not comment on that because my knowledge on that is limited, hahah.
