I do both. I did RTI before Crestron. Both have headaches. I have much preferred RTI wireless controllers to Crestron's offerings but outside of that, you would find that Crestron CRUSHES RTI and once you get past the initial concept of Crestron programming it is literally Simpl... the problem is that it is so open ended in comparison that if you are not an organized and methodical programmer, you will create more problems than you solve.

My favorite... Crestron DM. Expensive yes but try to do it another way while providing all of the same features and benefits you will spend the same with less reliability. It is not for every situation but when it is, there is no denying it.
