Would you rather have one Prolong Charger or two EV Peak CQ3 chargers?

I'm not that familar with the Prolong Charger. I've read on this Forum where some people have 4 or more EV Peak CQ3 chargers.
I'm guessing that for the cost of two or three CQ3 chargers, you could buy the Prolong System.
I'm using the CQ3 charger. I'm guessing that it gives you a more granular and detailed reconditioning process.
