If the degree titles are anything to go by I would say that you have chosen two rather different degrees. One has a focus on clinical work (remedial / therapeutic) whilst the other is research oriented (and appears to be a precursor for those wanting to undertake a PhD) after graduation.
Shouldn't you first decide what you want to study, rather than where?
To answer your question, Oxford Brookes is well-established psychology department with a reputation for postgraduate teaching. It also has (or at least, had) strong links with the University of Oxford's Department of Experimental Psychology. In the past, the two universities have pooled their intellectual resources to win research cash (including PhD studentships). Because of this, I have more faith in Brookes as a quality institution, but I haven't looked at the partnership projects for 2-3 years so I may be giving useless advice.
