Which is better SI1 or SI2?

The main criteria in choosing between SI1 and SI2 all boils down to price and quality. Let’s say, both gems have the same price and cut; in general, SI1 diamonds are clearer, but SI2 are cheaper. But still, some SI1 stones may have inclusions visible without loupe, and there are SI2 diamonds that are eye clean.
