I think it does depend of what you expect from your investments. For instance, I don't expect my investments to provide the income I need to live, I want my business provides all the income I need to live and grow the investments. So, I am using real estate and shares as a medium to keep my wealth. The basic idea is money from the business go to investments.

I strong believe that both, RE and shares, will growth in the long term, so I declare myself a mediocre investor. For me average returns are greats.

I don't know which one is better, I think they are just different. RE is great because its leverage and shares are great because it's the liquidity.

Just my opinion.

Cheers
