Some sheep don't seem to have a personality, but the ones that do totally make up for the others! We have Steve who loves attention and basically shows herself at the fair. She will also pout (and not show off in the ring) if she doesn't get a "cookie". Then there is Infiniti who is the first one to the gate to greet me (ie....check for goodies) in the morning. Bridget the bug-eyed Shetland who never stops yelling. Jazmin, the best bottle lamb I've ever had. She isn't pushy or overly obnoxious and she is soooo sweet and comes when she's called. She and her buddy, Moe, go to the children's barnyard at one of our fairs every summer. Galadriel (AKA Pig Sheep) is the fattest, pushiest sheep in the barn. She looks like she is pregnant with triplets even when she isn't pregnant at all. But even the ones that aren't "in your face friendly" have personalities. Hairball (don't ask ) and Dixie are both quiet and shy. Babette and Buttercup occasionally like to be pet, but usually prefer to watch from a distance.I wouldn't really say they have a personality. For me, they're friendly or they're not; shy or outgoing (kind of goes with friendly-ness); passive or aggressive; gentle/calm or high strung; etc. I mean, I love my sheep, but I wouldn't say they have "defined" personalities, at least, not like a dog or a cat.
As to Goats vs. Sheep....I don't know that one is necessarily easier or better than the other. Wool sheep require shearing, dairy goats require milking, etc... I'm not really qualified to judge from the goat side of the question as I only have one goat and he is not a normal goat. He prefers to keep his four feet firmly planted on the ground. He's a good goat now that he's realized that the sheep are not going to eat him.
If you do get some sheep, being in TX, a hair sheep would probably do better than a wool breed. A lot of wool breeds would do fine, but the hair breeds seem to thrive on shrubs and heat.
