580EX II Speedlite or YN-568EX + YN-622C

I am torn bettween getting the used Canon 580EX II speedlite (~ $400 USD) or getting the brand new YN-568EX and the 622C remote trigger (~ 290 USD). I currently own the Canon T4i, YN-468II flash and 430EX speedlite. What would you suggest 1). Use the 580EX II as master and trigger the 430EX and YN-468II for off camera flash photofraphy. 2). Use the YN-568EX, YN-468II, and 430EX speedlite on the YN-622C remote triggers? I might have to purchase additional set of YN-622C for the 2nd option. Thanks for your input.
