Does anyone have knowledge about the comparison of different FPGA boards?

I've seen the Mojo v3 from Embedded Micro, the Papilio line of dev boards, and the miniSpartan6+ from Scarab Hardware.

It looks like all these dev boards are pretty similar since they use almost identical xilinx chips. Ideally, I'd like to find a board for which there is a robust community, good support, lots of examples, and has enough capacity/performance to take on more complicated projects with increased learning/skill.

I'm leaning towards the Mojo v3 board, since it seems very easy and has shields to expand capability, but does anyone have any experience, recommendations, or "I wish I had known..." stories for FPGA development?
