Pick the one that's the best fit for you.

I picked a job a few years back based on "it'll look good on my CV" -- turned out to be the worst decision I ever made. That's not to say every job will end as badly as that did, but I realised quite early on that I just wasn't a good fit for the company, and they wanted a "yes-man" to say "you're doing everything right", not an engineer who'd say "this is good, but we can improve by..."

Picked my last job based on the number of people I had at the company, the offer and the general "vibe". Best decision I ever made.

Don't be afraid to interview at a couple of companies then choose between them. Don't pick solely on "this is the highest offer" -- pick somewhere that feels like it'll be good for you.

And don't worry about prestige. About the only thing that'll put employers off are long gaps in your work history that you can't explain. But that's not a problem you're likely to have with a grad position :)
