For me, as you have mentioned, Portfolio sealed the deal and it was the icing on the cake. As an extra bonus, CC members get access to Adobe Fonts. As a typophile and admirer of typography, being able to browse all those fonts in Adobe Fonts like super amazing. I even found a font for my 2019 logo from a familiar foundry called "Dharma Type." I pay 119-something annually, which comes with Photoshop CC, Portfolio, and Fonts which provides all utility to me and sparks joy. I'm definitely going to renew my subscription for 2019-2020 annual plan.
Being on CC plan, I no longer have to worry about shared-hosted web hosted. I don't need to mess around with CMS (I was using Koken and long before that WordPress). Basically, being on CC Photography Plan streamlined things for me.
Shared-hosting cost me annually close to CC fees. It's no brainer that I hop onto the CC membership, which comes with features and products sets I find immensely useful and practical for my professional photography.
