Firstly, you want to learn Bokmål, and that's what all of these resources are for. It's the more widely spoken and I believe that it is what is usually taught to learners.
There is famously very little on the internet for Norwegian.
I'd suggest actually buying Teach Yourself Norwegian (I've heard good things, but haven't seen/used it) or this one

I can vouch for that - stickers and flash cards included and an interesting way of putting Norwegian words into the English sentences in a way that you will clearly understand; by the end sentences are sometimes more than half Norwegian. Fun and easy to keep going, definitely good if you sometimes run low on motivation and dull grammar-intense courses deter you. Like I said, though, I don't know the other and can't say that it is any worse - just more traditional, judging by other TYX books I have.
There is, of course, the Pimsleur Norwegian:

But that is quite basic, I believe.
Unilang have a Norwegian course that I know nothing about, worth checking out;

Their Norwegian forum will also be quite useful, one of the posters (nighean neònach) has great Norwegian and is always helpful.
Lykke til! (Good luck!)
