The scan rate of is what drives the preference towards P10 panels. Current code and hardware being used limits use of panels to 1/8 scan rate on HUB75. There is some work in progress to expand this limitation which will open up more possibilities on what panels are supported. If you are interested further, search the forum for ColorLight and LINSN.

FPP supports 1/8 scan on 32x16 panels and 1/16 scan on 32x32, 64x32, and 64x64 panels, although the 64x64 I have seen are actually two 64x32 panels in the same frame with dual two sets of inputs and outputs.

Talking about P5 vs P10 in this context is like saying that you use 8mm LED's in your display, it means almost nothing.  The '5' and '10' are just physical measurements, they have nothing to do with the actual input signal which uses a HUB75 interface.  You then have to know what scan rate the panels are using.  There are 1/4, 1/8, 1/16, and now 1/32 scan rate panels.  The libraries that FPP uses only support 1/8 and 1/16 scan rate, although I am working on creating a new pair of channel outputs which can directly drive the commercial receiver boards that businesses use to drive these panels.  Once this code is added to FPP, FPP will be able to support all of the scan rates since the scan rate will be handled by the dedicated receiver board and not a general-purpose Pi or BBB computer.

The actual decision for using different panel Pitch is just distance to viewing.  I am a little closer to street and think P10 is not going to look as good as would be for someone else farther back in their lot.  That said, when I first looked at P10 panels a few years ago they were $30+ and now they are so popular ($10) it might be foolish to pass up on their value even they won't look as "high def" as I would like. 

Once this code is added to FPP, FPP will be able to support all of the scan rates since the scan rate will be handled by the dedicated receiver board and not a general-purpose Pi or BBB computer.

This is kinda the reason I have been holding off but also plan to approach panels as a video concept and not sequencing/channels and have not quite figured that out yet but hoping the new hardware move us in this direction.
