I have both, and I switch between them depending on the game. Games that I want more performance I’ll use the Go, as well as games that benefit from a larger screen like FFXIV. If the game has acceptable performance on the Deck, I rather just play on there since the device is more comfortable and the OLED screen is so good. The deck is also really useful for games that don’t have controller support due to being able to map everything super easily.
