The only drawback to a string loop is loosing about 1/2" of draw length. Other than that they are great. You are pulling in line with the arrow eleminating nock pinch. The string moves in line with the arrow eleminating the string whipping downward at the release. There is no torque on the string at full draw. There is much less wear on the string and serving.

A loop is definetly the way to go with a release.
