The correct answer to this open question is the following.
I think my life would be different if the British or the French had controlled Texas instead of the Spanish. First of all, different cultures, traditions, and customs.
Today, the cities would have had the architectonic influence of the French, for instance, would have established some forts or trade posts in the Texan territory. As the French interest was not really to settle the land, just to get big profits from the fur trade, the influence could have not been as strong as the case of England or as happened with the Spanish influence. Probably, just enough influence to have some beautiful French architecture such as downtown Nee Orleans or French cuisine.
