MICU vs SICU

It's funny to me that the MICU forum and the SICU forum are together because in my hospital, it seems like they are like oil and water. Medical residents are always bashing the surgery residents and vice versa. Different attendings, styles of medical managment, patient populations, MICU uses pressors and SICU uses fluid first, different vent settings, and the list just goes on and on.

I am SICU RN, but I have been pulled to the MICU more than once and I enjoyed it everytime.

Is it like this everywhere? Or am I just lucky?
