Hi all,
I have offers from following universities and I am not able to decide which one should I finalize. Please let me know which one you think is best and why?
1. London South bank University
2. Birmingham city University
3. Cardiff metropolitan University
4. Bournemouth University
5. Anglia Ruskin University

Thanks in advance.

I don't think there is a big difference between them. None of them have meaningful accreditation internationally. They are Freshers MBAs aimed at people returning to their own country. 
Bournmouth is a cute place, and a popular holiday destination. It will have the best weather and is very safe. 
Why not take an MSc in management at an above-average university?

Do you think a MSc is better than an MBA? I want to start my own business after a couple of years. Talking about budget I can afford around 10k only. If I decide to go with MSc which universities will you suggest?

An MSc from above average universities is better than an MBA from a below average one. Take a look at mastersportal.com and filter for Europe and £10000

Or use the FT Masters in Management 2019 ranking and add in the field called Maximum course fee (local currency)*  http://rankings.ft.com/businessschoolrankings/masters-in-management-2019
Good and inexpensive options look like the WU, Prague, Mannheim, IAE Aix, SGH, Cologne...
