Notion

Simple to input text and numbers. Terrific shortcuts for a variety of jobs. Excellent for including and embedding media. The app allows me to quickly photograph handwritten notes and store them in a folder I can sort through on my computer later.

Don't try to reinvent the wheel when it comes to table cell entry; if I click into a cell and start typing, it will replace the existing content (just like Excel does), and choosing cells is far more cumbersome than in Excel. The process of making a template is not the most straightforward, and it took me some time to master it.

Notion makes organizing and note taking far easier than other current options. Being able to organize pages into databases and tables means I can manage my work load as a type of list with all the notes on each piece of work contained in a page tied to that list. The elements such as code blocks also make adding reference notes so much easier to come back to and use in future. It keeps me very organized. As a non-enterprise user the options are still endless and provides a good case to bring others on board as a collaborative tool - especially when it comes to sharing process documentation.

Unless it's changed, there were some promising options of integrating with mail calendars but it didn't look like this was suitable for work mail / Office 365.

Without doubt its ubiquity (they claim you can organise anything within it) is incredible.

User experience is not that good. It is not comfort for the eyes.
Too many options.
Too many features.
Need time to learn and use and you ended up reexplain that too many time to your team OR you must buy Khe course about that product. And it's something you should really consider into your calculation of what that software cost.
