Minimum fpga dev-kit/fpga

thanks guys. Little more help required. Whats the difference between SoC (like DE1-SoC Board) and Board (like DE10-Nano Kit). Are not both standalone bootable systems, Can't i use tcp-networking,C/python code on both kits to interact with their fpga's etc. Is there any other major differences apart from LEs count or arm processor speed. Pls clear. Also i read i can use opencl to create and load fpga's on these boards as both are cyclone V and opencl supports cyclone V). Thank you.
