If you really want to use only free software and hardware, you should probably avoid the Raspberry Pi. While the specs and price point are very attractive, in order to use the Pi you must use a non-free binary blob.
Specifically, it is the GPU in the Pi that prevents it from being free; You can read more about it here: https://www.fsf.org/campaigns/priority-projects/reverse-engineering
This is the relevant section:
VideoCore IV GPU
This is the GPU used in the Raspberry Pi. While graphics processing and video decoding could be done by the CPU, the same software that runs the GPU is also required for the Raspberry Pi to startup. This computer is currently unable to even boot without nonfree software.
I thought about answering that way too. But then I re-read the poll which reads "Which is your Linux distribution of choice?" not "Which is your kernel of choice?".
In keeping with smart-a** comments to an innocuous poll, I was sad to see the various distros referred to as "Linux Distros" and not "GNU/Linux Distros" or "GNU/kFreeBSD Distros." Those may be very fine (and maybe esoteric) distinctions, but I think that they are meaningful distinctions.
