Same here. From what I saw from videos about the new AC and my experience with the mobile game, the game doesn’t seem as fun or interesting as SdV. Just pure grind, without interesting variations (and I don’t care about collectibles). The Gamecube version is looking more appealing because the town is already established, so you have to discover and interact with the world instead of starting from a generic empty island.
There is also a big difference in tag price. For the price of AC I could SdV on three platforms, or buy copies for friends to play with me (I did that once).
