ClickUp tries to do everything in one place, but that comes with a price: the interface is cluttered, there's too much going on, and finding what you need is a chore unless you're a power user. Even basic project management gets buried under layers of options, which slows down day-to-day work and makes onboarding a headache for most teams. On top of that, ClickUp is slow to load, which adds even more friction every time you use it.
Shortcut, meanwhile, is stuck on an old, legacy tech stack with a decade of tech debt. If you care about using something modern or want a tool that feels up to date, Shortcut just isn't it. The only thing it really offers is that it doesn't overwhelm you with endless options, but you're trading that for a product that's aging and feels behind the times.
If you have to pick between them for project management efficiency, neither is ideal, but Shortcut at least won't bury you in clutter or slow you down with endless menus. ClickUp just makes simple things too complicated and gets in its own way. If you can tolerate an old-school tool, Shortcut is less likely to waste your time with confusion or delays.
