Staxel does a lot of things right. It's a bright and cute take on the blocky Minecraft style, and there's oh-so-much to do. Staxel even lets you customize your world and home, much like Stardew Valley, and there are plenty of relationships to forge as you go about your business.
Your days are structured much more effectively than Harvest Moon and even Stardew Valley to an extent, since you've got plenty of time to do what you want even after all your chores are done.
So why is Stardew Valley better?
For starters, Staxel treats farming a lot like Farming Simulator does. It's definitely a business arrangement before it's anything else. Farming gives you materials you need to create buildings and develop your town — and you need a lot of materials.
That's one of Staxel's biggest problems: the grind for materials. Farming is made easy, probably to account for the grind, but having the ability to cut your farming tasks short so soon, and making farming just the means to an end, takes some of the satisfaction away.
Stardew makes you work for a while before you can even get the materials for a decent sprinkler that hopefully works every day. True, the goal of farming is to make money for other things, but in most cases, that money is used to buy more goods for your farm, or it gets put back into the town in some form or another. It's not just fodder for Petals (Staxel currency) and materials.
It's an interesting drawback given how the game starts off so similar to Stardew and other farm-life sim games, putting you in charge of renovating a run-down farm.
The socialization falls short as well. Villagers don't have personalities that pop like in Stardew, and they are admittedly a bit creepy thanks to the otherwise-cute aesthetic. They do play into the game's lore, but ultimately they come across like fillers more than interesting personalities to befriend.
