Arca-Swiss vs Markins ballheads?

Which is better? Arca-Swiss B1 retails for around 450 euros, while Markins M20 is around 380 and M10 around 350 with the shipment.

I know the specs, weight/max load is slightly better for the Markins heads, but I wonder what is a better quality heads? I hope I will be able to get a head that will function very smoothly for many years.
