Info on credit cards with best rewards program

[Will Zena]

I was looking this up in previous forum posts and noticed we haven't gotten a good response in years to this question.  However as a real estate investor and entrepreneur my businesses will be requiring me to travel a little more.  I noticed my credit cards (I have only two) have terrible rewards programs.  Please let us know in your experience what the best credit card rewards programs are out there for flying and hotel stays.
