The Intel wireless are the *best* supported under Linux: the drivers are open
source AND supported by Intel (actually ditto for Intel wired NICs -- Intel's
decision to provide *supported* open source drivers for their NICs is said to
have pissed off Bill Gates). I don't believe *any* of the other wireless chips
have vendor support open source drivers. They either are reverse engineered or
communitly written. Or else closed source or are wrapped MS-Windows drivers.
The only issue with Intel drivers would be the firmware, but I believe Ubuntu
distributes the firmware as a separate package.

Nvidia graphics cards are something of bitch in terms of support.  Yes, Nvidia 
provides semi-closed source drivers, but you need to re-build them when you 
upgrade/update your kernel.  OTOH, if you can live with hardware accel, the 
open source (XOrg) drivers work well enough.  In terms of driver support, 
Intel video is better supported (see above).
