Got my Mallard yesterday, and I am positively surprised. I don't have that much Hornby TT stuff, and most of it is from the first run last year, mainly the Scotsman starter pack. I feel Hornby has started to learn how to put these locos together much better. The engine runs much better straight out of the box than Blink Bonny did, all the details are in the right place, and the tender is considerably heavier, which was a problem for me with Blink Bonny. I use Kuehn track, and the tender tended to derail in the curved points, but Mallard doesn't have that problem at all. So I'm very please with my new loco (even if it means Blink Bonny mainly is demoted to goods service now).
