Super and Daima. I wouldn't care. I guess no Super would mean less discussion post-2015, but no GT would mean less discussion pre-Super. Though, GT came out in the US in 2003, so I don't think it rekindled online discussion like Super did coming out years after everything else and with an Internet that had much more fully penetrated into the human population
GT just has Vegeta and Gohan as dads, Gohan as a professor, Bra/Trunks/Goten older, the proper and emotive farewell thst really feels like goodbye and mortality even showing future generations far after the deaths of our beloved heroes villains and all of us viewers readers debaters and dbz fanfic masturbators (wait what), SSJ4 is cool I guess, more time with Gogeta (than vs Janemba in movie 12). So GT is more significant in itself than Super I'd say.
