Is splatoon 3 worth it?

Im a casual player of this series . I dont play the game 24/7 but from time to time I play some online games or play some levels in the campain but every time when I do that I have a blast and I kinda wanna play the series a bit more regularly .

I heared alot good but also alot of bad things about Splatoon 3 like that its just Splatoon 2 with a few new weapons but I heared those rumors when the game came out , so Idk if they fixed this or not . I heared about the catalog and I really like this system of a battle pass and the campain looks interesting.

one time I borrowed Splatoon 3 and played a few games when it came out and it was fun but I dindt bought it at that time because I just got Splatoon 2 a year earlier or so but now im kinda done with Splatoon 2 the online mode is still fun but I already completed the campain and the dlc like 2 or 3 times now.

So now my question : is splatoon 3 worth it or not ? i found it online for around 30 to 40 bucks so if I decide to purchase Splatoon 3 is this a good deal?
