This one from TI seems much simpler with less BOM and no precision resistors.

The TI example also does not use 3-pin LDOs :)
Evaluation kits are not necessarily built with the "best" components, they are quite often built with "sponsors" components. Take a look at any of the Altera evaluation boards. For example, several of the kits I have, use Linear Technology parts and have "Linear Technology" on the silk of the PCB. That is there not because Altera loves Linear Technology, but because Linear Technology provided the parts for the evaluation kit :)
The best way to select parts is to ensure that you have design tools for the parts. For example, Linear Technology's LTspice is a very good simulation tool and has an excellent Yahoo support group.
