After some careful consideration and analysis, the math says comfort.
A peasant's life in the 15th century was hard. Happiness and tranquility is implicitly expected in the question from having a loyal wife, but this happiness is relative to our experience in the present time as lonely, mostly virgin men, and this does not compensate for the harshness of life and its conditions during that time. A simple infection while hunting or chopping firewood could mean you lose a limb or die. Your life expectancy is short, and you're at risk for raider and marauder attacks. The lords, dukes, and royals can also kill you and your entire bloodline on a whim for so much as not making them feel important and regal enough when you're in their presence.
You won't be living in the past with full memory of your incel life in the 21st as a baseline to compare your new experiences against. You can't even conceive of electricity in your home. The concept of inceldom and its resultant suffering in the 21st century that we're experiencing will be completely alien to you. You won't be a peasant from the future living in the past who would be so grateful he has a 6/10 loyal and obedient wife. For you, in the past as someone who didn't come from the future, having a peasant wife living and toiling through life's struggles together will be a completely standard, peasant experience for you. It won't be this amazing thing that has a lower chance of happening to you in the 21st century, than riding a real life, literal unicorn.
Modern comforts and amenities have an extremely high risk of making you weak and dependent on them. The responsibility to condition yourself to live life without them rests solely on your shoulders. If you're going to die of hunger because there's no supermarket nearby, then you probably should die of hunger. Learn to hunt, fish, and grow crops/fruits/vegetables. One EMP blast and you may have no choice but to.
