Six posts down on this page, regarding the new Standard Assets Controller:
New Standard Asset Characters - Third Person page-3
The way I see it is an asset either satisfies your requirements or not. If it doesn’t, you don’t really have a choice except to make it yourself or modify and extend that asset. Character controllers are usually pretty complex and have to interface with many other systems in your game. A one size fits all solution is impossible. That’s why I recommended Kinematic character controller. It has a lot of solid and flexible functionality without any frills so you don’t have to delete or work around a bunch of features you may not need for your game. The standard assets controller is still very useful though. I have taken some ideas from the way they have implemented certain things for that controller.
