Change can be good as was the case when I first moved to Evernote -- I changed several ways I had previously taken and maintained notes knowing that I would end up with a superior outcome. Unfortunately, as I said, I've had to change my note taking habits for the worse, which usually translates to one or more of the following: waiting considerably longer to enter a note, manually write down notes, wait until I get to my desktop. Even on the desktop the new version runs considerably slower so I use the legacy version. If I had confidence the problem would soon be corrected for my situation, and I do realize not everyone is experiencing the same level of frustration, then I would wait things out.
I am currently reviewing Notion and it looks promising but I really need to load it up with notes and the type of templates I utilize before I can make an accurate assessment. BTW, I only use Evernote for personal use, not for business/collaborating.
