Out of those two? Probably Stingray, but a big shout-out for Parker. However Fireball XL5 was my favourite of all those, and my first love was Supercar.
PS: They've 'sort of' brought back Thunderbirds, (certainly the concept) but with cartoon dogs rather than puppets. It's called 'Paw Patrol', and the Jeff Tracy role is played by a nine-year old boy called Ryder.
by coincidence I watched the first couple of episodes yesterday of Thunderbirds since I was a kid. Blimey they hold up really well, the tension and pacing is so well done
