I've been thinking about this. I've never been on a liveaboard, but how would you choose? Except for online reviews... This boat was brand new... The big issue is that it's all chosen online, booked and paid in advance. And no refund if you just don't board (nor if it sinks, as it seems...). The crew had explanations for the tilting and it straightened out once leaving harbor. I don't think I'd have cancelled my stay to be honest. I'm also not very experienced but many of the divers on this boat were...
Several posters afterwards pretty much answer your question. Most of the liveaboard trips are pretty safe & enjoyable. However, like the saying “One bad apple can spoil the barrel”. So I just want to share my experience on 30 liveaboards (more than that if you count repeated trips on the same liveaboards, some were up to 3-5 times) without any problem that affected the trip. I had great times on all of them.
How did I get such luck? First of all, I don’t want to be a Guinea Pig, i.e., I won’t go on a new boat. Also, I read trip reports of those boats, including boat accidents such as this one, before deciding to go on a liveaboard trip.
No matter how you prepare for it, “Sh!t happens”. Sometimes I did get lucky timing wise. For example, in 2019, I reviewed Red Sea Aggressor 1 that seemed to show being a good boat to be on. So, I booked for December 2019. Guess what, the boat burnt down and sank in October 2019. Aggressor hired a temporary replacement, Scuba Scene, for my trip. That trip went well and I posted my trip report, here,
Trip Report - BDE Trip Report, 21-28 December, 2019 . Then few months after my trip, Scuba Scene sank too.

There are some physical attributes that make you leery about going on certain liveaboards. The one that got me thinking on this boat is the top heavy, long and skinny look of it. From the picture, below, the 42m long, 8.5m wide and 15m high above the water line just don’t make me feel relax to be on it.
