De1
De1 comes with the hybrid solution ARM SoC (capable to run linux)+ fpga inside the same chip, they are linked over the bridge called AMBA,
which is a bus, and it requires more effort to be used: it's not suggested, in my opinion, as first experience, as it comes with with more complexity
apart tastes, because tastes are personal tastes, and in this case I am fine with Spartan 6 LX9 (Xilinx), installed onto Papilio/Pro board
which costs more than De0 and comes with less resources, but I love it because it adds exactly what I want: fpga, dram, 48 I/O (to add a NVRAM)
enough BRAM to implement my soft core, and enough resources for my TAP
in short is up to you
