It would probably be best to wait until the other banks finalise their offers by the next week or so. Until then, feel free to window shop for better offers. 
If you're worried about any adverse movements in the share price then take the loan from the bank that gives you the highest buffer. The larger the difference between the margin of finance and the force selling ratio the better.

You can call CIMB and ask about their financing. I believe they will be doing the pink form financing.
If you need white form financing, you'll need to apply for a share margin facility.

CIMB will only finance the pink form ie if you're an employee of Maxis. If you need financing for the white form then I'm afraid you're outta luck.
