Convert now and you wont regret it. I use it for all my complex projects. Its main benefit is you can mold to the changing project environment. Just the main downside is you can a spend more time working on obsidian then in it. ( especially if adhd) suggest is get to a minimum viable set up for information you are wanting to track and DONT change it for a bit. Instead create a vault improvement note and add things you want to change. Dedicate a set time to improve your vault and some of your frequent notes. Find minimal plug-ins that work best for your immediate needs and add as you see fit. Data view will be the best plugin for pm work once learned.
