Hi Scott - I went through this a few years ago and created a spreadsheet of
my findings. I am with Erie for home, auto and personal umbrella but stayed
with Geico/BoatUS due to the spill issue. At the time, Erie told me that
the decision on whether or not to cover a spill would be made at the time
of the claim. That was enough for me to stay with Geico. I will send you
the spreadsheet separately. - Allan
