Sure it produce good results !! :)
It always depend what you want...in advanced modeling usually G1 is not enough
i have read here from an user in the past:Apple wants just G2 filleting in their stuff...(take a look at the edges of I-Phone )
..or imagine to model a car with lot of patches that need to join together without seams ;)
Let Michael to say something,if he's not too busy :)
hope this time no misunderstadings :)
