Easily the $50K route.
The $5K per month doesnt allow a lot for saving, and if you have any medical issues later in life (or just emergency situations that require cash), you could be in a real bind.
Earning $600K per year for 5 years minimum allows for a lot more security later in life, and you could even keep it going for longer if youd like.
