I think the Adventurer is worse because it doesn't imply any of that. It implies a character that is good at several things at once. They can fight decent, use a variety of skills, has a mix of languages and survival tools, and probably a smattering of magic. It looks more like a modern day survivalist than an Everyman, and probably would feel like a ranger or rogue hybrid.
As an aside, I'd personally like to see that 'hero with a special power" be used for special powers, not a schlub who manages to blunder though a campaign. If we're going to use unique origin stuff, use it as an excuse to have martials throw mountains and fly, not to let Baker's make skill checks with an extra 1d8 added...
