An offer you can refuse

I just talked to the VP in charge of projects and yes the job is a globe trotter with no return to my beloved city. Game over.

It's time to accept the other offer and write the resignation letter. Do I go with “I Sincerely regret……all the bets for the future” or “ This letter serves as notice of my resignation and commencement of my notice period as per the contract of employment….I wish to leave as soon as possible”.

Probably the former.
