Yes — but wait for the April update first. The Pixel 9 Pro XL is still an excellent flagship when these problems are fixed. The camera system is class-leading, the display is gorgeous, and the Tensor G6 processor handles everything thrown at it.

However, if you're buying in the next 1–2 weeks, make sure to immediately install the April 2026 patch after setup. The app crash issue is severe enough that using the phone before updating isn't recommended.
