That's like asking "what's the best flavor of ice cream?" Everyone has a different opinion.
However most people will agree that if you're new to Linux, Ubuntu is the best one to start with.
http://www.ubuntu.com/I'm pretty new to linux, and I dual-booted ubuntu on my laptop. It's my first try at linux and so far it's been good. My one major problem with it (which would probably also happen with other distros) is my broadcom wireless card not working at first. If you have any problems then try Broadcom Firmware Cutter. Search something like "fwcutter" on google. It might be a package in synaptic, but I'm not certain.
Broadcom drivers under Linux is a pain in the first place because they are Windows only and closed source. If you really need to use the fwcutter (only works with certain hardware) here is their website
http://bcm43xx.berlios.de/IIRC newer Kernels 2.6.24+ are shipping with a backwards engineered open source driver that works very well, gives almost out of the box working wifi, you still need to run a command that downloads the firmware for all the broadcom cards and then loads the one needed for your card. The main advantage this driver has is that wireless seams to respond better than if you used NDISwrapper and easier to setup than using the fwcutter tool and extracting the firmware yourself.
