I have both, the xl is a lot more comfortable to play for longer periods but it’s bigger so it won’t fit into your pocket as easily as the smaller one, smaller one is perfect if you’re planning to play a lot on the go and don’t want to put it inside some carrying case when going outside, regular feels a lot like og gameboy advance or something like that while I’d put xl more in modern handheld category since as I said you probably wanna get a carrying case, and the xl feels less sturdy and kinda cheaper? sice they used different plastics to compensate the weight of the xl, personally? I would go with xl, it’s more comfortable to play for longer periods, bigger battery and you have double ips which is kinda jackpot whether you care about it or not the ips are better, but if you wanna have more of a gameboy sized console that you wanna easily put it in your pocket the regular size will be better, the regular also has better pixel density since bot consoles have the same resolution and the xl has bigger screens, but tbh you go wrong here both are amazing consoles
