+1. I remember checking out Standard Notes and their longevity mission is very positive. They seem to have a solid product, but their approach just doesn't click for me.
Been using Joplin for a couple years. It's one of those few open-source apps that managed to find a golden ratio of functionality but still to the point, a coherent pleasant experience across desktop and mobile.
Missing a basic collab or note sharing functionality though. It's all open formats and that, sure one could hack around it, but more in the spirit of mutual access to encrypted notebooks for example.
When I tried the joplin app 9 months ago, the mobile app on iOS was just plain broken.
As far as E2EE note apps with mobile and desktop apps that sync go when I last looked in 2020, you have Standard Notes, Joplin, Inkdrop, Amplenote, Day One and DevonThink. I tried out Inkdrop seriously, but it wasn't better enough for me to switch and was more expensive than standard notes.
A lot of these apps are $5/month, and I feel like that is too much compared to the $3/month far more sophisticated utility apps like 1password are sold for.
For Joplin, review the sync settings. Sorry I forget which one it is but on iOS there was a bad default and once you change it the mobile app works like a dream.
No it was broken to the point where I couldn't even just write a note with a keyboard properly. Even if that was fixed the fact you have to change a bad default out of the box is indicative alone.
As a second data point, I've been using Standard for a little over a year now, and haven't had any syncing issues. Maybe I've been lucky, or maybe it's gotten better than it used to be.
I sometimes (once every few months?) get a duplicated/conflicting file-pair appear. It's a bit annoying, but not very annoying. Can't remember it happening recently.
After many years with google keep, evernote, standard notes, simplenote, org mode, plain files in git etc. I finally found joplin and couldn't be happier.
Yup. I switched from evernote which was syncing poorly to Joplin and it's been great. Writing ~daily notes for over 2 years between ~three devices and it's had a problem exactly once due to onedrive changing their APIs out from under Joplin
I wish more apps used git as a sync option. GitJournal is a great client for Android phones and then any editor on desktop platform works fine (plain text or markdown notes). I use it with vs code and Dendron.

It's a bit ad-hoc, but it works well.
