Thunderbird 1 looks very nice, although it would benefit by having landing gear, or even a display stand.
Thunderbird 2 is the biggest disappointment of the range as it isn't the right shape and has those awful circular intakes just like it's little Konami cousin. It does come with legs and a removable pod.
Thunderbird 3, like Thunderbird 2 isn't quite right, but it still looks good and gets away with it.
Thunderbird 4 is excellent, it even has cabin detail.
Thunderbird 5 has some nice detail, but could do with thinner upper antennas.
Finally the Mole, which does tilt, move forward slightly and spin by hand.
