And importantly, you know Excel/Sheets well probably. Other tools start at a major disadvantage in that they're competing with a tool you're familiar with. That's a powerful adversary.
I would place my knowledge of Excel/Sheets at the level you'd expect from a typical programmer - I don't know the keyboard shortcuts, but I know how to make pivot tables and write formulas.
My main issue is that the specialized tools always impose some sort of opinion on how ____ should work that is close to mine but different in impactful ways. Case in point, JIRA. With how infinitely customizable the columns are, it might as well be a spreadsheet with links to email threads.
That's selling JIRA short on how much the UX tries to do for you, but I'm intentionally making a point about how much overhead there is in paperwork generated by the fact that you're using JIRA. When I compare how much paperwork JIRA saves me vs. how much paperwork JIRA generates, I often find, even as a PM, that I come out behind. As a developer, I pretty much never feel like I'm coming out ahead on time.
I don't mean to pick on JIRA specifically because every bug tracker I've used has this problem, but JIRA was the tool I had to use for work for the longest time, so I wanted to stick to what I experienced firsthand.
