Speedo LZR racer elite vs Blue Seventy Nero TX?

So I am primarily a troker and i do the im. Which suit is better for the type of races i would swim. I have States in about 2 weeks and im swimming the 200im,100 , and the 200 and 400 free relay so which would be the better suit to buy? So far I've found a website that sells the Nero TX at $189.99 and a lzr racer elite for $195 so the prices are relatively similar. If you have actually worn both of the suits what are your personal experiences and reviews? thanks for the help
