it is just personal preference. someone may view modding as a hobby and to show off their creativity and personality.

for me as long as the modding do not cause harm to other road user, it is fine. if i found it is an eyesore for me, i avoid looking at it.

i have no problem with jerk now with my amt. the car has to get use to a certain driving pattern. you cant simply change your driving habit from smooth driving to full throttle to achieve high acceleration out of sudden. then it will jerk like riding a mad cow when you try to drive slow again especially at gear 1 and 2.
