4k Wacom Cintiq Pro 16 or XP pen ultra OLED 16?

Hey curious if anyone can make a recommendation on which device to get, looking at similar price for both on the used market. Will use for csp primarily making game assets like characters and environments. Currently using old huion 13” 1080p. Like the Wacom name but like what I’m hearing about the xp pen too and OLED sounds appealing (although maybe at the cost of reliability over time). Let me know what you think. Thanks!
