I have a base deck with a 1TB SD card and haven’t wanted for the more expensive model except for once. Baldurs Gate 3 absolutely thrashed my deck between shaders and massive save files. I eventually symlinked the save problem away from internal storage to SD and it’s been smooth sailing ever since.
For what it’s worth, a newer deck might be on the scene soon with a better WiFi chip, but the current one has been fine.
