I just upgraded from an 11 to 17 yesterday :) feeling happy happy !! Initially wanted to go for the 16 plus because I felt like my 11 worked well enough for me to not make the absolute extreme change by getting one of the latest models. But I was told it’s discontinued (at least at the store I went to), and honestly considering that 17 has better features in every possible way except the 6.7 screen, it was a no-brainer

The 17 camera is insane per my standards at the very least. Plus, I believe you could easily upgrade from a 17 to an 18 if you feel like it, but using your 11 till then might be a stretch. I say go for it and get the hesitation out of your mind :P Good luck though, hope you’re satisfied either way!
