I am going to be honest I have not actually used notion much but the features in Buildin are great. I previously used a different tool but stopped because they added AI and it became too messy. It makes more sense to me that something that is suppose to organize thoughts and ideas ... to have a very clean and not distracting user interface. It makes such a huge difference in being able to make whatever it is you want to. It did not take long for me to understand how to use it and when I realized how much I like it I came back and upgraded my tier. I am currently building a database for all the workings and documentation for a business. It is easy to see pages and navigate. It is also straight forward and simple to share. Highly recommend it especially if you dislike clutter and value a clean distraction free page to work on.
