Seconding the suite warning with the specific way it goes wrong, because it is slower than people expect.
Nothing dramatic happens. What happens is that over three years you accumulate: a few extra apps from a catalogue, a couple of manual fixes you made at 1am and did not write down, a database that has been through five major upgrades, and a background job that has been quietly failing for months in a way the dashboard shows as a small yellow line nobody looks at.
Then an upgrade needs a clean state and you discover the state is not clean.
None of that is an argument against running one. It is an argument for two things: keep a written note of every manual change, and actually read the job status monthly. Both are boring and both are the difference between a five-year install and a rebuild.
