I'd say that I like the third one the best, I like how it would give you a logo and a word mark. The one you ended up picking is another one that I like as well. I'm not sure how those contests work, but make sure you get the raw file from the designer, if you just get rasterized images you'll be screwed when it comes to resizing/making changes. Hopefully they weren't made with Photoshop, Illustrator is a lot better for making vector graphics. It's probably a combination of the two programs.
As a side note I know that tons of designers despise 99designs since it really devalues their work. It says that you received 365 logo concepts for $299, that's less than a dollar a logo ^^ I'm indifferent to the whole idea, you get lots of work for cheap, but you give up getting to communicate and direct the design process of the client. As well as their is incentive for designers to crank out massive amounts of work without much thought so you most likely aren't getting their best work.
