I am more productive at home. I worked a home/office hybrid schedule for years. Office days were always throw-away days. Little got done on those days. Real work got done on my home days.
It's probably better for my company for me to be home.
I'm starting to think, however, that I'd be much more mentally healthy in an office. I think it may be unhealthy for me to sit alone all day without the distractions of an office.
