NJ,

As far as the 60 sized being better, yep, Bigger will handle wind better. You will also find that larger planes are easier to see and just plain feel better on the sticks, but along with bigger is bigger cost.

Take a 4* 40 up in 10mph winds and land it crosswind and it will fight you some. Now take a 4*60 up in hte same wind and watch it land very much the same as with no wind, minus the need to be a little faster on landing.

Again all of this my opinion
