imperviously

I know what it does. The thing is, there are somethings that sometimes are better, but not that noticible and not worth the extra bucks or double the money unless i was doing some serious racing. i do plan on racing at a club level for some fun, as rc alone is never as fun as it is with others.
i do like to win, and i do strive to get better and tweak my rc to be better. but im not here to spend things that are not needed also, so i was just wondering if it was a noticible difference between the two.
