you can look at it this way, making a big jump up (NUMERICALLY) from 2.56 to 4.10 would be like getting an extra deep 1st gear, and giving up third gear. You are talking about a HUGE change.
The 4.10 will:

1) Get much worse gas mileage.
2) Will launch much harder off the line
3) Will be turn much more rpm at 65 mph.

And for everyday cruise driving, it will be fun up to about 50mph, notsomuch above that.
