My $0.02., develop your own pros/cons list as no one knows what's more important to you, than you. Example, I absolutely hate lag in software, probably an unhealthy amount... I also enjoy a headphone jack, but that's less important than software to _me_. At the end of the day, no phone is better at software and camera than the Pixel 2 (I have non-XL, coming from a Samsung Galaxy S3) and that's what I think ultimately creates the Pixel appeal because literally every time you use your phone, in an app, to take a pic, etc, you get that top-of-the-line software experience. How much does Samsung's superior hardware matter when apps lag or freeze and frustrate the user or they're running a 6-month old security patch level?
Also got mine 50% off during Verizon's Black Friday deal last year, figured the savings was worth the locked bootloader. Then we got an unlock method anyways in December so win-win, half price + unlocked BL now. Is the P2 worth full price to you? Who knows. But good luck whatever path you choose!
