The strength of the knot (or splice) is a bit of a red herring. Modern line is sized not by breaking or working strength, but to provide adequate reserves after chafe and sun rot. Any decent knot will provide adequate strength. A good knot will minimize movement and chafe, as well as allow adjustment of the line.
What is nice about the passing the standing end of the line through an eyesplice, with or without the extra loops around the piling is that the line can be adjusted from on board the boat. That works best on transient slips. In your home slip, I prefer having the eyesplices on board at a preadjusted position so that I can quickly get them on cleats in the right position when I am single-handing.
My gripe with tying up to a piling or bollard by looping the line a couple times around a post and then passing the standing end of the line through an eyesplice is that the line loosens and tightens as the boat moves allowing the line to chafe and work its way down the piling.
