Zeus-Dios always gives me slightly more trouble than I expect him to. I'm not confident enough in my damage to try to blow past Hera without leader swapping, but if I do the switch I lose a turn of damage boost on Zeus to healing back up from his pre-emptive damage, and one turn isn't really enough, especially if I have to use an orbchanger on Hera. This time I just let him get his shield up and tanked hits until I could swap back to Beyzul (much easier now with all the skillups) and stalled for my skills. When I swapped back and blew him away I suspect it only worked because I got a skyfall, without that I think he would've had a sliver of health left and I would have died.
