In my experience:Philosophy -- because it would stretch my intellect in ways that I could see as being useful to whatever career(s) I choose, because it's extremely interesting to me, and because it would keep my writing skills in check. The only downsides are a. I would feel really pretentious telling people about my major, b. I'm concerned that other Philosophy majors would also be snobs, and c. I might fail and/or end up jobless.
For what it's worth, most people are either mildly interested or scoff when I tell them I'm a philosophy major. I don't think you have to worry about being pretentious when telling others that it is your major. No one takes it seriously or knows about it enough. Also, that would be the least of your worries. Philosophy is incredibly rewarding and you're constantly challenged by the material you have to read. At least, I am. But it requires a lot of critical thinking and going around in circles to put out a clear, well thought-out paper.
These should be your biggest concerns: the intensity of the content and the amount of reading you have to do to understand a concept. It's not always necessary, but you'll want to know what you're talking about when writing papers, which often entails reading the subject material. A lot of people skate by because they're smart enough and because they have a lot of other commitments, but it's easier when you do the reading, as laborious as it is.
That being said, it can by trying, but a lot of fun.
And for my more biased opinion on colleges and their relative worth:
Despite what is said about the worth of a college degree, I think it's absolutely worth it. The biggest concern most people cite are the finances, but it's not all about money. I say this as a poor kid who's going to be paying off her loans for the good majority of the rest of her life. Yes, I'm bitter about it sometimes, and yes, I highly recommend staying in-state so it's less expensive. (Please, please stay in state if you can help it. If you're lucky, your wanderlust has not totally consumed you, as it did me.) This is very circumstantial, though, as out of state schools can offer generous scholarships and in-state schools don't always have the programs or majors you may seek.
Yeah, I forgot to clarify, that was only if I would go on to grad school. I would never go out into the workforce with an undergraduate degree in philosophy. That would be insane.
