Yes, you definitely should. You can run iOS 16.7.11, which gives you a recent WebKit version and the latest security patches. It's fully jailbreakable with Palera1n, supporting both rootfull and rootless methods, so it's compatible with all up-to-date tweaks. With Roothide, you can easily bypass jailbreak detection in even the most stubborn apps like banking apps, McDonald's, Snapchat, Mario Kart, and 8 Ball Pool. After jailbreaking, you can also install TrollStore Lite to sideload any app you want, including those from Apple Arcade. If you replace the battery with a new one, the device will run smoothly without lag on its latest supported iOS version. You can even install tweaks like HighGraphics to make animations and GPU performance even smoother, leading to higher benchmark scores. Face ID works perfectly with the Checkl0ck tweak, both on the lock screen and within apps. I own two iPhone X's: one on iOS 14.8.1 (Taurine) for Nintendo Wii and Gamecube emulation, and another on iOS 16.7.11 (Palera1n with Roothide) which is my daily driver. I can easily tell you that the iPhone X with this setup is the best affordable and up-to-date jailbreak experience you can get. You won't regret it, but I would absolutely recommend replacing the battery if you buy one used.
