Worth what exactly? What do you think the X could do better / smarter / faster / "cooler" than your "very old 6S+"? If you're unsure rationalize it. Take 5 minutes and write a Pro and Contra list. If you find more pro points, buy it. If not, you're good with your 6+ ;)
PS: I'm saying that from a perspective of owning an iPhone 5 and I stood in front of the X. I tried it out and found out that it doesn't excite me much when holding it in my hand. So, my decision against it was pure gut and intuition - contrary to what I suggested to you ^^. Yes, the 5 is pretty slow (and probably the 6 as well by now) but it works for what I'm doing (camera, browsing, some apps)

Level 1 for the project #weekdaykickoff which I started to solve a pain/problem I personally have - though I've received feedback that such a product would be relevant to others as well. However, my main attention (in terms of income) is on client work (#copygiraffe #stolenvoice) which is why I'm taking the slow and steady road towards a level 2.
A mixture of paper, macOS Notes app, Evernote, and OmmWriter+Scrivener synced through Sync (privacy-aware Dropbox alternative) in case I do morning writing sessions (brain dump).
I'm most proud of having made a 27-minute short film because I went through the whole process of film-making: from writing the screenplay to casting, filming & directing, post-production, premiering the film to a selected amount of people in a cinema and then making it available for free for everyone to watch online on YouTube (www.youtube.com/watch?v=_6Ypz…) and Vimeo (vimeo.com/64427137)
