I was thinking the same too,
pools: standard, smart, stealth vs alpha, beta, gamma
unique id: smart code vs bestmixer code
the step by step procedures and everything else also looks similar too,
the difference is just this mixer has different color theme

and having a dashboard for it means you will need to log and share some transaction details
btw, your miners' fee seems a bit high, 0.00045529 BTC per receiving address
