I had the pixel 3xl but traded in for Note 10+ , I now have the 3a which is a great device. What you will be giving up is water resistant rating and wireless charging if that dont matter save the 100.00.
You're also giving up Visual Core, which will slow picture processing time (mainly HDR+ and Night Sight) way down, and the 845 flagship processor for a mid-range processor.
