I interviewed at both western and touro-ca, and ill give you my two cents:
I didn't like Western. A lot of the staff seemed disinterested in 'pitching' the school to us, the place had a very high-school like vibe, and they would never get back to me when they said they would (although this isn't uncommon among schools). My interview went well, but nothing about the school really jumped out at me. During the morning introduction with the dean, the focus seemed to be on how great the school's reputation was, and that rubbed me the wrong way too. I tend not to like it when people use prestige as a selling point.
Pomona's also an absolute pit, even though most students commute from nearby places like Chino Hills or West Covina.
I liked Touro-CA, although it wasn't without its problems. From the get-go, they were honest, enthusiastic, and they really made an effort to answer our questions about the school instead of just dangling pamphlets in our face. The school is a little decrepit, as its located on a former naval base, but the setting is absolutely gorgeous. Students were happy, friendly, and I really liked the fact that you get to dissect cadavers as part of gross anatomy instead of having them prosected. The campus is small, but views of the bay and the well-groomed grounds more than make up for that. If I had to comment on one thing (problems with rotations aside), it'd be that I felt a little isolated there. There is a single paved bridge from Mare Island to the mainland, and it really is the only drag in and out of there if you're going to be commuting (which is what most do).
I'd choose Touro over western because i think I'm a better fit. Check their match list too. Although it isn't as impressive as Western's, it sure as hell ain't bad at all, especially for a school that new.
