Bass vs Vioin (Davie504 vs Twosetviolin)

I was expecting to see response by twoset violin but I saw this one. He responded first faster than twoset violin and played the challenge on the spot.

But for your professional opinion. Which is better? Bass of violin?
For me, violin is good for romantic and soft music but the bass is very versatile
