Wales, hands down and I say that as a one-eyed loyal Wales supporter.
Many reasons - the red is a great colour, it's not green with a yellow stripe painted on it and it's second only to the All Blacks in terms of good looking kit.
What would make it better would be to get rid of the Prince's white feathers (sigh) and bring back the dragon and THEN we'd have a kit worth playing in.
Plus SA has some kind of four legged food group on theirs.
I've always disliked the colour red, unfortunately green is 'her indoors' default colour whenever she feels the need to by me a nice shirt...fuck I hate green shirts but they still win out over red.
I always thought the welsh logo was celery stalks (another food group)?
Tricky one! In the end the simplicity of the South African jersey won it for me. Although I think it's unfair to judge jersey on stand vs jersey on player....
