What LAMP is best for Windows?

A VAR wants to work for our company. He says it’s best that we install a LAMP server, but I’m not big on Linux yet. If he leaves us, I don’t want some strange box sitting around with web applications I can’t even control.

I Wiki’d a bit and found several versions even for windows, but which is best? I saw that WAMP seems abandoned and apachefriends.org/en/xampp-windows.html looks quite current and seems like I could manage it 🙂

If I install and give him access to only an admin panel and FTP access to those folders on a XP box, will he be able to work? Do I have to give him access to the CLI?

Since the only white-paper I found here was from 2005, does anyone have some experience?
