Ok, I don't watch either of these shows, but I think I'd rather be stuck on a starship than crammed in a phone booth with another guy (the Tardis is a phone booth, right?).
Its a police box. Totally different beast.
Anyways, to the question. I think I have an idea as to where the op was going with this. I mean, no argument, the Doctor is an interesting traveling companion who could literally go anywhere and anywhen he wanted. Of anything he is a loud character and even the sixth one had charisma to him.
Meanwhile, Spock is unemotional and anti-charismtic, and the Enterprise, while a well-built ship, can only be in certain places, and can't travel in time.
However, something that has gone unmentioned, and this is important in relating to others, is the fact that Spock isn't going to treat you like a kid. In fact, he's not a domineering person. Stubborn, sure, but dogmatic? Not really.
Th Doctor, even the more 'human' incarnations like the fifth or the tenth ones, can be quite dogmatic. Before someone comments on his shifty morality, he isn't a moral absolutist (chaotic good done right), but he can be quite preachy.
Another character trait that can't be subscribed to Spock: arrogance. It comes with the territory, but still, it takes gall to say to a room full of panicky people "I'm a nine hundred year old time lord, that's why you do as I say."
Lastly, Spock doesn't regenerate. What you see (a green-blooded elf with super strength whose heart is located under his armpit) is what you get (seven year itch notwithstanding) and always what you get. The Doctor... well, Whovians remember Rose's freak-out in
Christmas Invasion when the Doctor changed form
and personality? He went from being a sever leather-clad baldy with two hearts to a giggly fetishized autistic with two hearts. Something to consider.
Both are smart rationalists, and both will cover your back in the hairier moments, but the question stands.
I'd go with the Doctor, though I note reasons why someone might travel with Spock.
