OK, PatM, i said I would tie 2 loops...one with the ends swapped and one with the ends matched (the way i was taught). I just tied 2 small 6 strand loops so as not to waste too much material.
There is very definitely a difference in the appearance of the string. When the ends are matched the splice just seems to flow into the body of the string.
Not so when the ends are unmatched. My very first attempt years ago was tied this way so I knew there was a difference. It kind of looks convoluted in appearance with no natural transition.
The unpracticed eye probably won't see a difference.
I don't think there would be difference in strength.
Anyway, tie them the way you want as will I. Whatever pleases you.
