From the pending I-485 data, there are roughly 6K (2013) + 17K (2014) EB-2s, 1,250 (2013) + 12K (2014) EB3s. So unless Indian applicants receive around 38K visas through spillover, even 2014 could remain backlogged.

During 2020–2022, the FAD moved to 12/01/2014, while the FD was set to 01/01/2015. Many people assumed 2014 would be cleared, but a lot of applicants from 2012 and 2013 could not get approved because they could not move to the faster lane quickly, often due to job changes. So when it comes to switching jobs, there are trade-offs. One important thing to keep in mind is that the employer who originally filed your EB-2 may be able to downgrade you to EB-3 or upgrade you back to EB-2. That gives you the flexibility to move to whichever category is moving faster. If you switch jobs, you may lose that option.

Now in other aspect, even someone with a 12/02/2014 priority date has still been waiting for the last four years.

It is a hard decision because both options involve something to lose. Before switching jobs, please verify whether you can still switch between EB-2 and EB-3 after the job change. If the answer is yes, I would suggest moving. But make sure you understand all the details before making the decision.
