That's a tricky one. I think that an MBA from Warwick would carry more weight with employers when you're looking for jobs. However, the nature of the Westminster program means that you get more face-to-face interaction, which is great for leadership and soft skill development if that's what you need in an MBA.

I would talk to the schools to see if your goals mesh with their offerings. If you will need post-MBA career support, ask them what they provide, since many online and part-time MBA programs don't really provide much. They should be frank with you.
