I used to have 10s for strings, but I have some issues with my pinky and I have gone down to 9s. The other day, I raised the action quite a bit, since the guitars are already easy to play with these strings. It made a big improvement in tone - less rattling and buzzing, while still being easy to play. I don't know why I didn't do this before.
My observations - I would rather have 9s and high action than heavy strings with low action. It works so much better for me. Just my 2 cents. If you have strong fingers, you might prefer the opposite.
Lesson learned: experiment! Only by testing different things will you know what suits you best.
