Which Is Better For Visa Abuja Or Lagos, And Why?

I will be paying for a school in UK soon and i hope to receive a necessary documents for submission at the embassy here.

But the issue is a friend told me it is better to apply for visa in Abuja other than Lagos, that there is high hope of not being refuse visa in Abuja than Lagos, but i don't know how far that could be true.

So anyone that know much about this should please hint me if that's true and which eva is better please tell me your reasons.
