Barney means that you can't set a timer for the main light and moonlights separately. I'd always intended having a look at this to see if it can be altered but never bothered. I too really like my Orca and would happily recommend it with the already mentioned caveats. I also had a JBJ but have sold it recently. It suffered the same moonlighting issue as the Orca.
One feature on the JBJ that could be a good thing or a bad thing is that the filter chamber inlet is set towards the top of the waterline. This means that if the inlet gets blocked for any reason (I suffered from hair algae in this tank) then the filter chamber could potentially run dry which could expose the heater therefore damaging it and if the glass of the heater were to crack then it could potentially be a safety issue both for the keeper and the tank occupants. . Mine nearly did an a couple of occasions. This is exacerbated if you are not efficient with your top-ups particularly in high summer. The level of the water in the chambers goes down but the tank level remains constant so you don't necessarily spot it. You just have to make sure the grill is always clear.
Other than that it was similar to my orca but bigger.
