A friend of mine booked this trip and I was too busy working to get involved. I soon found out once arriving and furthermore, on the first dive that I was in the wrong place. The dive masters are extremely controlling (if they're really even dive masters) and if you aren't looking for someone to hold your hand and treat you like a four-year-old, then don't choose them.
Scuba Junkie on Mabul is a very 'commercial' place and again, for people who've never been scuba diving before. The rooms are a little nicer than you'll find elsewhere on the island but personally, I don't think that's what it's all about.
If you want a local and a family feel, I found another place called 'Homestay' which was awesome. The only thing I regret is that I found them after spending my time and money in the first place with scuba junkie!
