I haven't built with them - just kicking the tires but have been impressed with the sales process of Couto Homes. Very attentive and giving me all the info I need in a timely manner.
Some (not all) of the builders at couto used to work for Clarity in Fort Worth. The team I'm specifically thinking of was VERY fast but lacked attention to detail. Don't know what you're building but if you go with them I'd advise checking the work frequently and being annoying about the details.
I'm not in the business but a very close friend is and your experience is probably 50% the company you go with and 50% the actual builder/PM assigned.
