Last Friday was very chilly. The cool wind gave me a huge craving for hot pizza. The sweet smell of burning wood always makes me very hungry. Figuring out the Ooni Karu 12 Vs 2 debate took some time. Let us look at what makes these ovens special.
Ooni Karu 12 Review

This classic oven started my whole pizza journey. It is a solid beast made of shiny steel. You can use wood, charcoal, or a gas burner. It changed my weekend dinners forever.
Pros and Cons
Every tool has its good and bad sides. Here is a quick look at this classic model.
| Pros | Cons |
| Bakes a perfect crust | Lacks a glass door |
| Very easy to move around | Needs extra gas burner |
| Reaches high heat fast | Ash cleanup takes time |
Mastering The Fire After Months
Using this oven for months taught me a lot. The learning curve is very real and takes time. You have to watch the open fire very closely. One time, I burned my dough to a total crisp.

Once you learn the tricks, the results are great. The smell of hot crust feels like a real bakery. My friends always smile and ask for extra slices.
Recommendation
This oven is perfect for beginners who want simple cooking. It is great for those who love playing with real fire. It is not good if you want to walk away while baking.
Ooni Karu 12G (Gen 2) Review
The newer model feels like a fancy sports car. It has a nice dark finish that looks amazing. They added a glass door and a handy heat dial. You can watch your cheese melt without losing heat. It really steps up the outdoor cooking game.

Pros and Cons
This newer model brings some very fresh updates. Let us see what works and what does not.
| Pros | Cons |
| Glass door saves heat | Costs a bit more money |
| Handy built-in dial | Feels slightly heavier |
| Cooks with door on gas | Still needs gas add-on |
Loving The Upgrades After Months
Getting this new oven was a very big thrill. The built-in dial takes all the guess work away. I do not have to blindly guess the heat anymore. Watching the dough rise through the glass is pure fun.

You see the exact time the crust bubbles up. The dark paint hides dirty soot very well. It stays looking brand new for many long months.
Recommendation
This model is perfect for folks who love easy viewing. It is ideal if you want better heat control. It is not good if you are on a very tight budget.
