Once you have a strong CV, it won't make much difference whether you have a degree or not. Your experience and track record are far more relevant as far as career progression goes. For personal satisfaction reasons, you may still want to finish your degree. Based on having already done 4 years, it appears that only your thesis is outstanding. So it wouldn't be a great deal of extra time. With your experience, you should be able to pick a more suitable thesis topic and supervisor. In my experience, choosing a compatible thesis supervisor is most critical to successful thesis completions. You will need to be candid as to why your previous attempt was "wrong". Good Luck!
