would help getting a better tone ?
Not a "better" tone, but a heavier gauge set of guitar strings is going to have a little bit more output than a lighter gauge set of guitar strings.
Not if you go from 009 to 010, but if you put on a set of 012s you will here the difference.
For some guitar pickup/amp combinations this might be good, for others not, just try it.
For me the feel of the string tension is more important.
