Most universities need you to have at least 2 supervisors. During your 3 years journey, in case one of the supervisors quit the job, change university, go overseas do postdoc, take unpaid leaves or whatever reasons, then u still have another one who know and follow your progress.

Pick one SV who is strong in the methodology that u use, another SV who is publications in your subject matters. As such it will avoid conflict between SV, as they know their boundary. Pick those SV with at lease few PhD candidates graduated under him/her as the track records.

My case is opposite

Feeling so tension now whether should continue or not. My family queries me a lot whether my research title is good enuf to secure me a job after i grad? LOL!!

Don’t make the mistake of keeping problems to yourself. Everyone hits a difficult patch at some point in their graduate student years, so having problems is nothing to be ashamed of.

Would you tell us your research topic?

If you ask me, I don't really bother if my supervisor is young or senior in his/her respected field. Getting an experienced and influential supervisor in the respected field is just an added benefit. I prefer to weight whether my supervisor is interested with my research topic, level of commitment and working attitude. And also his/her research philosophy.

You'll have a massive headache dealing with supervisor that isn't really committed in your research.
