Nadav,
Both types of investments will serve you well whichever you pursue as long as you stay the course and continue investing. The Bogleheads (Vanguard diehards) and Bigger Pockets crowd have plenty of millionaires among each of their ranks, and I'm sure each invest in both asset classes as well as others. Not bad company.
Find out what percentage of your assets you want in stocks/bond and what percentage in real estate and be conservative at first in your risk tolerance. Real estate will require more of your time from a management standpoint but it can possibly accelerate your wealth building through the use of leverage.
Pick up a copy of The Millionaire Mind by Thomas Stanley if you haven't read it already - he talks about the wealth building aspects of a sample of decamillionaires and most didn't build their fortune through publicly traded stocks but rather through their own companies (including real estate).
Best wishes!
Mike
