EB2 or EB3 ?

[Sameer S]

Will appreciate an advice. I am on fourth year of H1B with masters from US and 7 year experience (5 years with current employer). I am a Full Stack Developer but my employer is filing under EB3. Is it better to switch employer and wait for a year and get filed for EB2 or file it under EB3 now and look for better opportunity ? 

Thanks
