What is the difference between shift counter and binary counter ???

How will it make difference in the HDL code ?
 

To see the difference, you can have a look at the following links

See GOOGLE for "Johnson Counter"
 

the binary counter need more decode logic than shift counter,so that's why when coding state machine ,the suggested state code is one-hot, thus the decode logic is small,although many FF are usde , in FPGA FF is sufficient
you can see the difference from RTL level schematic

Added after 5 minutes:

you can read this book: verilog hdl synthesis, a practical primer by J.Bhasker

Binary counters are considered as Asynchronous counter while Shift counters are Synchronous counters.
