The link didn't work....
I voted for the TGUK trio. I don't think it is 1 person that makes the show great, but the chemistry between the 3 of them. They all work really well with one another and you can see that they are really good mates (most of the time) rather than colleagues. You would expect that though considering how many years they have been working together for Top Gear and getting that balance right.
A few years from now, I feel that all of the other Top Gear shows will show the same level of chemistry between the presenters. I just hope that the current UK presenters will still be working together, as I don't think it will be easy doing a like for like replacement for any of them...
