What is the best program for teaching english abroad?

I might want to go to another country and teach English. What are the most legit and easy programs for doing this? I know I can just google this, but I was thinking more along the lines of personal experiences (or friends experiences). I was looking at JET in Japan but it looked sketchy given that they place you pretty much anywhere, including random villages hours away from the more appealing cities.

Note: I only speak English.
