And should you be changing your username to tanklesswaterheaterface?

Others have basically answered for me. The positive is the water sitting in a tank needs to be heated, then cools, then reheated. With tankless this doesn't happen. In a house with many people this is less of an issue as the water is being used. In our situation there are just two of us therefore we'd be fairly inefficient constantly heating the tank.
In a larger household another positive is you don't run out of hot.
The drawback is running the water to get the hot. We don't have the recirc, never heard of it until today in fact. You just get used to having showers back to back so the water doesn't cool down. You can get the sandwich effect where you start off hot, then get a cold sandwich in the middle before the hot water comes back. That's only if you allow the water to sit in the lines for a few mins. The recirc would eliminate this.
Regarding the water temps, 120 is plenty hot I find. Edit: I just checked the system and I can increase mine to 140.
