There are many burger eateries on Oahu, but not many are consistent. I have tried Burgers on the Edge and have found them to be very inconsistent. The amount of sauce varies and your burgers could be burned and crispy at one time and soft and raw another, it just depends on the day.
Teddy's is a great burger and I often visit this often, but the help is inconsistent in their ability to take down accurate orders and deliver.
Kua Aina has it set for perfection each time you go there. I would like to see them having more avocados instead of selling out too quickly, but I guess this is how you keep things fresh on the menu.
Try these folks, they don't need any more advertisements because they are so busy, but among those mentioned here they are the best!
