Which RE investing strategy has the best overall return vs risk?

[Mano Chidambaram]

Here is a question for folks who have experience doing various investing strategies through the years. I do understand that these strategies span the gamut of totally active to totally passive participation. If you are capable of investing in any of these strategies, purely from an overall return perspective, which one of these strategies, i.e. SFR, multi-family/small apartments, investing in Syndications, mobile home parks, notes, etc. have folks seen the best bang for their buck? Thanks
