Hi Stathis
I totally sympathise with you and thought it would be worth sharing my Evernote history. Also, before I begin, a disclosure - I moved to the Apple world entirely about 10 years ago so I do not need a cross-platform note taking app.
I first started using EN over 15 years ago (pre Phil Libin) and since then I have accumulated over 20,000 notes covering my personal and business life. I used EN to go paperless and for to dos/reminders. I became a premium subscriber when this was introduced and remain one.
About 3 years ago I decided I didn't like v. 8 introduced under Chris O'Neill's watch and decided to move to Apple Notes for my paperless requirements and Reminders for to dos/reminders. Where I used to share documents out of EN for non Apple users, I commenced using OneDrive. I have retained EN for two reasons - tags (I made extensive use of tags for my business use of EN and couldn't import these into Notes) and the ability to change the creation date of notes (which Notes currently doesn't have).
Since moving from EN to Notes, I have moved from being an evangelist for EN as a paperless tool to being one for Notes. With the changes coming to Notes with iOS 15 (tags in particular), Notes is just getting better. Also, Reminders is a better tool for me for to dos and reminders than Evernote was.
So why do I prefer Notes to EN? I think the main reason is it incorporates a largely traditional file structure (i.e. you can go to 4 or so levels of sub folders). We have all been brought up using sub folders in personal computing and I believe this paradigm remains more user friendly and intuitive for most use cases than tags. That is not to say there is no role for tags - I have almost a thousand of them in EN for which I have a legitimate use. Personally, I think EN is fundamentally flawed in only offering two levels of folders (i.e. stacks and notebooks). Other than for reasons of sentimentality/tradition, I cannot see why EN doesn't replace the concept of stacks and notebooks with folders and with the option of multiple layers of sub-folders while retaining their rich legacy of tags.
The other main reason I prefer Notes is its simplicity and its attractive UX. Unfortunately, to me at least, EN has become very complex and not very attractive.
Putting it another way, in summary, I enjoy using Notes and I no longer enjoy using Evernote.
BTW, does anyone know whether:
1. The creation date of Notes can be changed in iOS 15?
2. The Note import tool in iOS 15 will enable EN tags and associated tagged notes to be imported?
If the answer to these questions is yes then with some degree of melancholy, I will be letting my Evernote subscription lapse.
