family calendar

The kids are getting older, which means more and more activities are filling up our calendar.  Our small dry erase calendar just isn't cutting it anymore.  I can't fit all the things in on some of the days because it seems like everyone is going in a different direction.  I decided it was time to buy a bigger more organized calendar to keep up with everything that is going on.  I considered trying to make my own so it could be totally customized for our needs, but I decided to give one of these pre-made designs a shot for this year. I was torn between this calendar

and this one

Ultimately, I decided to go with the first one because I like being able to see our plans a month at a time, instead of by the week.  I have a feeling in a couple years I'm going to need the second type of calendar as we add more and more to our family schedule, but for now I'm hoping the calendar I chose works out for us. 
What kind of family calendar does everyone else use?  What do you love and hate about it?
