For me it is also any advantage I can get to keep up with my boyfriend. No competition, just hoping he feels slightly out of breath when I am panting for air. Unfortunately he is the weaker one in a group of bike friends too, so he also tries to optimize as much as possible.
It will make you go faster. It only makes any difference at all if you are competing for something, whatever level you are.
But if you like cool bike stuff, great, go get it.
