Diffuser fins or RTR style?

Whats up guys. looking for opinions on a diffuser. I have a 2015 oxford white GT PP premium.... have been looking at different diffuser set ups for awhile. I cant decide whether to go for the RTR style... or just bolt on some fins that i've seen from various vendors. I have a black/white theme going on I think it might look cool to put black fins on a white premium bumper to add contrast...but don't want it to look too busy. Or just go with the RTR kit since its the most aggressive option imo. thoughts???

I like cosmetic mods, but I try not to overspend on them (not easy).
I would go with bolt-on. Easy enough to upgrade to full diffuser later if you want.
