Everything here works.
Depending on what you use and what you want - some work better than others.
For example if you’re looking to get girls into bed then IO is probably worse value than TUTH (assuming you are good at icebreakers in conversations anyway).
If you give us more background on yourself and what you’re hoping to achieve then we can help out a bit more. Things like age, what you do, how you like to meet people, are you already in a relationship, etc.
