I've only skimmed the studies. Maybe other studies have different outcomes. But the long term studies I read suggest that shares or property do similarly in the long term with property doing better in general.
I think personally property is less risky. But rental isn't simply property it also business with cash flow. I would say the rental part of property is high risk. Problem with a tenant has the potential to negate returns on rental income. So you could argue having property you don't rent has a similar return in the long term for far less work.
What buy and don't rent out, in the hope that the market raises to sell on for a profit?
I'm thinking more of a steady income stream to subsistence my pensions.
Surely buying a plot of land with no houses, which was a "thing" a while back would be better and buying a house? there's barely any upkeep costs... a business man has purchased most of the land around my village and just holding it, he made a tidy profit on some of it when HS2 was planning to use some of it, but when HS2 plans got changed; I believe he brought the land back at a much cheaper prince.
