I assume you are talking about distance learning.
I didn't know Kennedy exists before reading your post. in my opinion University of Wales doesn't sound too good on your resume. I think there are too many private education providers that are entitled to award Wales degrees. I don't know how Wales can assure high quality standards under these circumstances.
The Liverpool online MBA is run in cooperation with Laureate (
http://de.wikipedia.org/wiki/Laureate_Education). They look like a solid company with some years of experience. "University of Liverpool" sounds like something real (to me). Their business school also offers taught MBA courses.
None of the programs is accredited by AACSB, AMBA or Equis, but Liverpool has an accreditation by EFMD while Kenney does not seem to have any international acreditation.
Liverpool's program is much bigger. They enrol 1,800 students compared to Kenney's 670.

That being said, I have to make clear that don't have any first-hand information about the quality of the courses offered.
