Wetsuits for Triathlon. Xterra Vortex 3 Sleeveless vs Orca S3 sleeveless?

I compete in triathlon and i would like to improve my swim time. I am definitely going to get a sleeveless wet suit. I am looking at the Xterra Vortex 3 sleeveless with the TRIFUEL coupon is $150. The Orca S3 is around the same price. I am looking for a durable yet functional suit. Which one would you suggest or any other suit would you suggest? please keep them under $200
