#Emacs is probably the greatest tool there is. Unfortunately, it's so different to other tools you know that it's complex to explain without running yourself for a couple of weeks.
Just watch some random videos online to get some impression of the potential.
Other #PIM tools are like Playmobil. #Orgmode is like Lego. You'll build your digital workflows according to your requirements. It will adapt and change as your world does. You'll never lose any data because of some tool discontinuity or proprietary Markdown syntax elements.
Don't be intimidated by the Org-mode power: you should start lean and it's easy to do so: https://karl-voit.at/2020/01/20/start-using-orgmode/
Without serious trying yourself, you can't have a qualified judgement about this. I had to realize it myself as I began to understand Emacs only by retrying 10y later.
