As someone who has both a regular full-size electric oven and an air fryer, I use my air fryer a lot more and would 100% recommend it.
It’s not just quicker, it’s a lot quicker, considering you don’t need to do a 15 minute preheat like regular ovens. On the other hand, my air fryer only needs 2 minutes.
Saves a lot of energy - I mean, who doesn’t like to save energy? Especially when I want to reheat stuff, I’m done with the air fryer - even cleaning it - all in the duration a conventional oven would take just to finish heating up.
In my experience of cleaning both ovens and air fryers, I’d say an air fryer is easier to clean, simply because the surface area is a lot smaller. Sure, you can put an oven tray in the dishwasher, but don’t you clean the rest of the oven? As for an air fryer, you may be able to put the tray/basket in the dishwasher, depending on the model, but even otherwise, a couple of quick swipes with a paper towel does the trick.
In saying that, newer tabletop electric ovens also double up as air fryers, such as the one by Breville - so if you have the space and don’t have an existing oven, get one of of these I’d reckon as they would be more versatile.
