Moving with family... good and bad areas of Temecula/Murrieta, CA?

My husband and I grew up in Rancho Cucamonga and we are now looking to purchase our first home in the Murrieta/Temecula area. We have 2 young kids, 4 and 2 1/2, and don't need a ton of space for our first purchase. My husband will be commuting to Riverside for work. We went looking with a realtor all day yesterday and I am still torn between all of the areas we looked at (he was a little biased since he lives in Temecula and he feels that the Temecula school district is the best). I need help from other locals. What do you think of either area? What communities do you think are the best to live in? I know we looked in the Red Hawk and Vail Ranch of Temecula as well as Northstar Ranch of Murrieta. Any comments on those? Any specific borders to stay in or around would be very helpful as well. Thank you!!
