Tubular control arms vs rebushing

When I ran stock stuff I had the QA1 uppers and lowers. the uppers made a noticeable difference.

Now I have a alterkation.

Having run both there Rocco, how significant is the handling difference? Is it worth the cost of the upgrade for what would be a daily driver and twice a month 1/4 mile car? Or even for spirited driving on windy back roads?
