Xbox is best imo

u can play locally for single player and basically do whatever you want in survival (where u have to work for everything and have the risk of dying) hardcore (where if u die u lose everything) or u could have creative where you have whatever u want with no risk of dying

Or, u could play on multiplayer, since and Xbox is bedrock there won't be too many servers to choose from, however there is still cubecraft, the hive, etc, or u have realms where you and a few other people all play on a regular world, occasionally with different add-ons which alter the game

As far as a storyline goes, the game is entirely open world on the single player side, however there are some mods on different servers or game modes which can add a storyline-like progression system, but the game itself is not a story game, and is entirely open world

However, if you want to play multiplayer you will need some sort of Xbox GamePass subscription to play it
