You are absolutely getting biased opinions b/c the question is mostly subjective ... mostly. Most people who would actually choose Houston over UT live in Houston, went to UH, or have extremely close ties to the city. If they want to work in retail, they may also be pulled by the compounding rotation, which is unparalleled. Let's completely throw out the opinions from people who claim one school has a nicer faculty/a faculty that cares more. These students either didn't actually get into UT, have close ties to the city, or are trying to convince themselves that UH is the correct place for them. To the people claiming that UH is better for pursuing a residency b/c it is close to a medical center ... that's completely wrong and misguided. Also, thinking like that and putting all your stock into one medical center for residency is foolish.
First of all, it's about performance. If you demolish the coursework, ace the Naplex and law exams, volunteer all the time, have a ton of experience, etc., you will have a good shot at residency. Having said that, residency positions are highly competitive and continue to become more so, b/c pharmacy schools continue to open. In other words, you are going to run up against others with similar credentials.
So what happens? I have worked with a residency director/director of pharmacy and am also married to a transplant pharmacist who is a preceptor at a very highly regarded hospital. She has input on which students become residents.
I ate lunch with the residency director on many occasions and we talked about this very scenario. He said that school attended does play a role in selecting an applicant for residency, especially when two candidates are on equal footing. My wife and I have discussed this as well, and she says point blank that if two candidates are relatively equal, they consider the prestige/ranking/program of the school attended. Both the residency director and my wife said the school attended is a good indicator of the students ability to handle the workload. We're all subjective to a point ... we all know UT is number 4 and Houston is tied for 49th ... they know this too and they do consider it.
If you want to be close to a medical center ... righteous ... more power to you. I love that UNC, Ohio St, and Kentucky work closely with medical centers and it was a big plus in my mind due to the extra hospital experience I would gain and networking, especially b/c every little thing can help differentiate the students from similar pharmacy schools when it comes to residency positions. If you think, however, choosing what is considered to be an average pharmacy school in 49th ranked UH is going to get you a residency over a UT student b/c you have ties to the center, I would really reconsider and not make my decision based on that.
If you want to make your decision based on residency, I would look at match rates and try to speak to/email/get in touch with somebody in a position of power who makes/helps make those decisions. They can better help you choose the correct program than future/current students throwing out opinions and statements about what they've heard from the people they work with/know. I've seriously heard people say they chose a school b/c another school was in the "ghetto," yet they had never visited the other school. These are the kinds of things you'll read when sifting through some of these threads ... scary.
