Well, they were by comparison, which was sort of what the whole thing was about. They said so themselves. On the other hand, when they got tired of the smell of corpses in Rome (they stayed for three months) they gathered Roman gold and crossed the Adriatic and conquered a good bit of that area as well. Marvelous mercenaries, and would be for another five hundred years or so.
What is not yet entirely realized is the extent of international trade at the time. The fact that Spanish artifacts turned up in this dig is one example of this. If the Celts were after gold in Rome, why? Because it was pretty? No, because it was tradeworthy. What Julius Caesar would conquer in the Gallic wars three centuries later was a civilization, not a confederation of tribes, and Roman law overlaid on it would provide the basis for the Middle Ages.
Being of Celtic heritage myself I have a certain sympathy for the whole thing, except perhaps for the human sacrifice (which the Romans would still be at during the Punic Wars, and yes, two of their victims were Celtic, the others, Greek. They buried them alive. I'm sorry I took that course in Roman Civilization...) And when, in the end, they migrated to Boston and took up basketball, they started a whole new...wait, what?
It's pretty and doesn't tarnish AT ALL. I don't wear gold on my old hands any more but I still wear gold earrings and around my neck a gold "Crusader" cross that I got in the Holy Land. I LOVE my cross.

and that boston tribe was most powerful when lead by Larrycus Birdium.
Longer than that. The Gallowglass mercenaries were a mainstay of European armies well into the Renaissance period.
