I don't really think Toney is better than Jesus but I do think there are attainable strikers who are better than Jesus. On his day Jesus is unplayable but he's always been a bit hot and cold and we seen the cold ourselves at the end of last season. Now maybe as he hits his peak years those dips get shorter but I do think it holds him back from really being irreplaceable in the way Saka, Odegaard, etc are.
There are also days where I think I'd love Giroud in this team, a big strong back to goal striker who can bring the attackers in and play quick passes around the box. Jesus does that in his own way but not with his back to goal and against a low block I'd love that quality in the team as an option at least. That said I don't think Toney really gives you that.
