I have a Tribute and I'd find it hard to imagine that the US model is significantly better (I'd not turn one down though). I think the necks are a bit anemic looking on the Tribby and mine isn't light but it's very well assembled and sounds superb.
Such a versatile bass, more so than a P I'd guess, a strong output too even in passive. I like the way that such variety is available even before you reach for the tone controls with neck/both/bridge : Parallel/Series : Passive/Active/Bright Active switches (3).
The pups and electrics are the same as the US models too.
I'd get one over a P bass personally
