I've had several bids from reputable painting firms to paint my house
exterior. Each provides the choice of either Sherwin-Williams or
Benjamin Moore paint. My house has wood shingles and the existing paint
is in fair to good condition, except for the color! The type of paint
will be flat Latex, with satin being used for wood trim and window
frames. A prime coat will also be used.

I haven't seen a comparison recently between these two paint companies.
Which would be better for my house? I notice that there are several
lines of paint for each company, for example Sherwin has Duration,
SuperPaint, A-100, WeatherPerfect, etc. How do these compare? I see
that Duration is a heavier paint which might require special application
techniques, but what about the others? Are all colors available for
all lines of paint?

Similarily, Ben Moore has Moorlife House Paint 105, Moorlife House Paint
N105, Moorcraft 183, etc.

If anyone with knowledge can help me choose, I'd sure really appreciate
it!

Jon.
