Push for Exec, or relicing key characters in the base teams?

Hey guys, I’m playing regularly for about a year (the acc is much older, so it is a salvaged account), my question is, I have a lot of key characters unreliced (DR, GAS, GG) which could make my teams in GAC stronger, however as for now (low bronzium) I dont really miss the relic levels to clear, but more like from the low number of competitive teams. So the question is: should I bring up the core teams (or at least the cores of the core teams) to relic, or push for Exec having all the requirements at 7 star. Any other recommendations are welcome
