I know what you mean. Rugby has evolved and not for the better in many people's eyes.
Although I would say that there have been a number of good Welsh players who have still managed to bring their skills into the modern era and make the game watchable.
Gibbs being one of those, Shane Williams another.
Jonathan Davies made a massive success of going up north in what is considered and accepted a much tougher code.
Younger people will mention these before BJ, Gareth Edwards, JPR et al.
As has been said before on many occasions, it is nigh on impossible to distinguish who was better than another if they were from different eras but BJ has been hailed by many as the best of his.
