Ummmm, what's the difference? I recently got some size 35 needles (holy cow they are big!), I needed a quick birthday present for my friend who requested a scarf. I made her a cowl & she said " I love these infinity scarves". I didn't twist it, not even sure how to do that. I didn't knit it in the round, I sewed it together.She really liked it so I guess that's all that matters.
