Weird Question: Would you rather your MD be someone you despise, or someone you love?

I am dealing with something weird in IB.

I am an associate at a BB that is verticalized and pretty much only work with 1 MD. The old MD I did not like. He was a bad people person, did not treat anyone with respect, was arrogant, extremely condescending etc. My life was easy though, I would just submit stuff, and not really care. He would be mad all the time so it never truly mattered and I didn't care. Had rude comments and remarks but I would just submit my stuff, turn his comments, and go home and get a check. Thats it. Stress was low because I was just outputting and not giving a shit and getting the job done. 

However, that guy left and a new MD is in his seat. This has been a literal like night and day difference. My new boss is amazing, and is probably the best boss / mentor / coach / teacher I have ever had in my 27 years of life. I am not even glazing. This guy is so thoughtful, considerate, the nicest guy ever, is hilarious, so charismatic. He is the man. 

However, in terms of stress somehow my stress has absolutely skyrocketed. He is not more demanding or anything, I just give 100x more of a shit and effort since I respect him so much and like him. I do not want to do poorly and upset him, or make his life harder in any any way so my life has become so stressfull. My past MD I hated so I legit did not give a shit at all. Would just submit and collect checks and thats it.

Does this scenario make sense at all? Can anyone relate? What would you rather have.
