I think 1. matters a lot here. If you do have sufficient funds to go by a few months, I don't see why you can't get a fresh job if you quit without an offer. I've done this before and am in a similar phase but working on my own startup. Having free time would allow you to think about many things, relax a bit in this stressful life and relearn algorithms and work on side projects. You will be more focused and determined to pass the interview, it's like the final exam that you cannot fail. Bear in mind it may take 1-2 month to get the job, however you may even hit the big four after preparing well. As for many people who say recruiter ignore applicants without job, I would say ignore them! Or you could approach recruiters/founders via linkedin which can be far more effective.
