All three have the exact same board inside of them.

[WarheadsSE]

P01 - Pro - black, has wireless (and thus PCIe)
P21 - V3 - Black - no PCIe
B01 - "Classic" - white/pink - no PCIe

It's all relative to if you need/want the wireless to be built in.

There are apps/services for that, and there are several GUis etc. This isn't Ubuntu though, so you will have to setup & configure them.
