Definetly go gunite. It will probably last longer. Make sure you read the fine print with regards to warranties and follow-up maintenance visits. Also, ask around and see who your friends, neighbors, etc. used and gage their experiences. Additionally, get multiple bids. A question I asked each one was "if your company did not exist, who would you use?" Some liked the question, some didn't. Those that did not were eliminated from my list.
I live in Crowley, TX which is just southwest of Fort Worth. We used Pulliam Pools. They are a Fort Worth based company and I am not sure they build in Plano. But they have been outstanding and there service is impeccable.
Good luck and keep us posted.
