Each game system has its own target market
Which brand is better for you?
Xbox is more focused on power and house systems rather than portables. This is clearly seen as their pre-released console, the Xbox Series X is claimed the most powerful gaming system. They also excel in media features with online streaming services like Hulu and Netflix, and many features that are missing in the Playstation and Nintendo systems. Controllers are decent and while the game library is not as big as Playstation, you can play exclusive games on your PC if you want like Minecraft and Fortnite. This is, however, the most expensive console in the market so far (Xbox One X).
Playstation is almost as powerful as the Xbox. However, it is focused more on competitive gameplay. Many of Playstation games are competitive titles such as Overwatch, Call of Duty and more. It even has streaming capabilities so you can show off yourself on Twitch. It has the broadest gaming library and even VR. Big deal for you right? However, the lineup is mediocre. Firstly, there is the PS4, which is ok, but it doesn't have the power that we expected in 2020. You may think of switching to the Pro, but the media playback is bad, as there is no Blu-ray playback. Which is frustrating as it already supports 4K. Also, it is not as powerful as you think. At least it is cheaper than the Xbox One X.
Nintendo focuses on innovation and fun instead of competitive play. They invented countless things like analogue sticks, motion controls etc. With the Nintendo Switch, they made one of the most versatile consoles of all time. They invented HD rumble to make gaming more immersive. However, they have the smallest game library, and for streamers, no luck for you as there is no video capture. And Nintendo, why there is no Bluetooth?
