I used the note 4 for 3 years and still loved it but I changed carriers and had to get a new phone so now have the note 8. I have a good case and screen protector and have never broken a screen yet and dropped all of my phones plenty. I wear cargo pants for work and always carry my phone and never had a problem with breaking anything.
I work up my contracts on my phone and use it to attach pictures, make notes directly on the pictures, email clients, watch football games, and it's the only way I access this site. (Thus all the auto correct typos) Having the s pen is a must have option for me at this point. Nothing like having clients sign your contract electronically right on the spot and emailing it before you leave the house. Makes for a very professional impression. I can't have a phone without the pen and I hate iOS with the heat of a thousand suns so not going that route.
I can highly recommend the note 8. I loved the note 4 and didn't think it could be improved but the note 8 is noticeably better. If they made a note 4 and just put the note 8 guts in it I'd be even happier though. I loved being able to swap out batteries and now I don't have that option but the bump in performance is worth it.
