Everyone should occasionally use Google Takeout to back up their stuff, but non-tech users don't understand this.
I use my own domain and private email service but I do run my blog on blogger. But, I have done the experiment of converting Google Takeout data for my blog and hosting it on my own server. My default is to use blogger because I like how comments are handled.
Services that Google and Facebook provide can be useful, but I view that as a small add-on to my own web properties.
Edit: I also find it convenient to sometimes use gmail, but my important personal and business email goes through a separate service that I pay for.
