SNA is super modern, efficient, and small, while offering great service. Everything is within a couple minute walk, at most. It is clean. It is literally a rectangle, divided into 3 terminals. There is no possible way to get lost. Delays and cancellations are not very common, and usually related to issues with the incoming plane. Baggage comes out super fast. It is the best airport I have ever used and I have flown a lot. A gate change here means walking an extra 10 steps. Seriously.
LAX is the scourge of our beautiful state of CA. It is quite literally the worst airport in the state, possibly the entire west coast. It is old, run down, dirty, crowded, slow, inefficient (baggage takes like an hour to arrive on the carousel), staffed by rude people, and a traffic nightmare (the terminal is a horseshoe shape and it takes forever for an Uber to get to you after you call it...like 45 minutes+ most days.
SNA is worth, IMO, 50% more in airfare just to avoid LAX. I can use either airport. I pay significantly more to fly out of SNA when I travel. I like LGb too, but only go there when I fly Jet Blue.
