I don't think the French one is that special, 'être honête', its just good running rugby. I think I may have scored one like that myself when I was at school (maybe!)
The Barbars one is much better, displaying much better skill from much deeper on the pitch and then a real injection of pace only right at the very end.
(However, IMO you can only really judge whether a try is good (or great) in the context of the particular match. Rugby is all about the battle you have with your opponents over the course of 80 minutes)
