Lushaka vs SSS?

Pre-farming planars for when they give out DHPT next week and want to know which is better, Lushaka or Space-Sealing Station? I'll be running him with Phainon and I have Cerydra with Lushaka. Is it better to have the energy regen and use the ATK boost for the hypercarry, or is it better to go with SSS for the ATK boost directly on DHPT?
