After 2 years of technical experience should I go for a normal MBA or an executive MBA?

Based on your question, it sounds like you have 2 years of technical experience and only 2 years of experience total. With that little experience, consider getting management experience rather than going for a degree. Do technical project management.
 
An emba would be totally inappropriate and any school who accepts you into an emba program with only 2 years of experience is not one worth going to. They would see you as a cash cow.
