Personally, I like real estate a lot more because my returns are lot better using a long term buy and hold strategy w/ standard leases. I have proven to myself that this option will far outpace the alternative, which for me, is investing in the SP500 index.
Like you pointed out, an index fund will provide a steady set it and forget it approach. Whereas real estate requires a heck of a lot more effort, time, coordination, etc. That effort and time should be worth it. From my point of view, if you decide to pursue real estate - you should be making a great deal more money using your cash in real estate vs. your cash in the SP500 in order to make it worth it.
The most important aspect is how much %return you get on the $ you invest. Less important - is how much of an asset you own (if you own 10% of a million dollar real estate asset or 100k of a stock, its the same equity!). Sure you have control over a larger asset, but its leveraged. Which means if the market turns or something unbearable happens, you not only lose the money you have invested - you are potentially risking the 80% that isn't yours! All real estate investors should be very aware of this fact. The leverage is great as a tool, but it comes with real risk.
If I'm getting 12% return on my real estate equity and 10% on my stock equity - sure the wiser choice is to go with the real estate option. But is that 2% worth all the extra effort?
20% certainly is - but 2% maybe not. That's a personal decision you should decide and then prove that to yourself its actually happening. My guess, without knowing anything else, is that you may make a bit more in the coordination you are doing, but you are risking a lot more and spending a lot more time than your safe alternative which is the Index.
