I disagree with the fact that the title screens are too simple. In my opinion, a title screen should be simple. I've seen too many games where the titles are so crowded, you don't know what to look at. Not a very welcoming first look at your project lol. But then again, that's just my opinion ^^.
If you had to pick one, I'd go with the first. Nice and clean. However, I'd follow the advice given by WhiteRose and some others. Try and mesh the logo in more with the background.
