Hey there,
First, congratulations on getting a job offer, much less several. Keep this in mind as you continue down the line because this means something; your skills are good enough that companies are willing to hire you. Not just the place you interned for or some mom and pop place noone's ever heard of but large companies. This is big. Very big and you should be proud of that.
Now, on to the dose of reality.
Companies, regardless of who you work for, are always, always, always going to try and pay their people as little as humanly possible to get your absolute best work. Every time. It's the nature of employment, so don't feel as though your only prospects are these. Since you haven't signed to anyone just yet, the future is wide open.
Having been in a similar situation several years ago, I went with what I /wanted/ to do. I joined up with a company that didn't offer me much in the way of benefits or pay (I was making near minimum wage) but the people were great, the field was something I knew and enjoyed working in and it also had a lot of (paid) off time. I used that time to farm out the skills I had learned in life and on the job as an independent contractor. This gave me stability and an easy fall back if I couldn't find work, which did happen occasionally.
Between my independent jobs and the firm I worked for, I pulled in about 65k a year. There were times of famine and times of plenty, but given a chance to do it again, I wouldn't even think about hesitating. As an independent contractor, you have a lot of control over the amount of pay you receive for your work. You take on a lot of responsibility too, but that's part and parcel for any business (which you would be). If you're going to do this, though, get good at accounting and saving.
All this said, decide what your long term goals are. Where do you want to be in five to ten years and what method would get you there fastest while not turning something you enjoy doing into something that you hate. Put some feathers in your cap when you can but don't sign yourself over to something that'll become drudgery, burnout is dangerous and can turn even the most passionate of loves into a nightmare.
Not the silver bullet you might have been hoping for, I know, but it's something that only you can really answer. I hope this was in some way helpful and wish you all the best of luck.
