Ridge vent is more involved to install. Box vent is lot easier.

That is total horse-****.

For a ridge vent, you take a radial saw and cut the decking from one
side to the other to give you about 2" gap at the very peak. Naturally
you set the blade so you don't cut the rafters.

It's easy to deal with the felt and the shingles. The vent itself is
easy to nail in place.

Box vents require more fussy work with the tar paper and shingles.

And no question that ridge vents give you more even air flow, and they
draw air from the very top of the attic (box vents are set further down
from the peak).

Flowing air does not know what kinda vent it is.

I still say to use the lightest-colored shingles you can get away with,
and go with powered fans instead of a lot of passive roof venting (but
still have as much soffet venting as is possible).
