What is your preferred product management / roadmapping tool?

My college aged nephew (studying comp sci) swears by ClickUp. I asked him why – he said it was the only task mgt system that everyone emphatically used and is very popular in the younger set. I will try it out and see what it’s like. I’ve used Trello and a self-customized version of a very old SalesForce install that we modified like crazy (don’t recommend it, but it worked for what we needed).
