Toolstation sell the plain ones - no o-ring

Are they used for different applications? I'm guessing the one with extra o-ring is the better as it's another seal?
Only need about 10, screwfix only sell in packs of 50's, but if the screwfix ones are better I will buy them. Are both ok to use in compression joints as well?
