If you're so vested into microsoft's products you should stay on windows. There's always going to be that one thing you can't do for people like you, so why bother? For the rest of the world, office for mac has been amazing, and works perfectly. The people who I got on mac (around 4, I believe) are pretty heavy Office users, and they haven't complained once. They have, however, actually said to me that they're shocked by the difference between what they're told about mac and how it actually is, and they quite literally thanked me that I showed them mac.
Office for mac is perfect for 99.9% of users. You can always bootcamp, but like I said, if you really need to use all those obscure features you know from windows, then yeah, stay on windows.
