Since you're staying in JB, your best bet are universities with presence/offices in Singapore.

Check out Southampton University in JB, if they offer an MBA program there.

Notwithstanding logistics, the best part time available in Malaysia are the Nottingham and Strathclyde MBA.

Check out UTM as well .They have a good MBA program too .

In JB why not https://www.insead.edu/master-programmes/mba! Highly recognized and great ROI

worth is justified by ROI.
The value of MBA does not lie on the coursework.
ppl in School A vs Ivy/Oxbridge studies the same case study for management courses.
for Econ and Finance also pretty much the same content.
the value of MBA comes from interaction with your fellow classmates building a network, your Alumni!
if U fail to network in a Top Uni, your ROI will not be good.

Masters/Phd is not useful if a person has good performance in his job. how is that useful if you can be good with your job with just a Bach?

if u want to break into upper management, it depends on Alumni and networks.
if u married someone at VP/CEO family, it can gain entry to those places.

In ppl in upper management from avg Uni or from Top Uni?
in your daily work, do you get face time with upper management to justify you are indeed better than your manager and deserve the promo? off work do you party/golf/drink with ppl up there?
if a person is great and somehow you get upper management to recog your greatness, where U get your MBA don't matter. Issue here is how to get your upper management to promote you over your boss over the other person? If U performed well at work, manager claims he lead well and qualify for a promo over you. he lead well and upper management needs a leader. U having a MBA is a worker not a leader. You have not proven yourself to be a great leader but your boss did.
Would your boss, said to his upper management that you deserve all the credit and you should leap frog over him. or at least move to his level.. where is he suppose to go if place isn't opening up? put yourself in your others shoes would you do that? if U are the odd ball who would, will avg joe do that? U will understand your chances.

In top Uni, thru Alumni and networking with fellow classmates.. they know you and your potential. One they have work with U those Homework/project, two they grad from same uni and they understand what you can bring to the table at minimum even if you have only met them in Alumni dinners.

don't be confuse with recognition by the country edu system and recognized by the company and getting a job. They are 2 different things.
recognized by a country edu req is often low, most uni can meet the goal.
recognized enough to get a good paying job... not any uni can meet your goal
