I know on upgrades that apex hands down has more options and it seems better put together in terms of different modules and probes. I know someone who has the reef keeper and has no problems your just limited with modules. They don't have as many as apex. However what made me choose the standard apex over the jr was the jr can only handle up to 8 modules I believe where the standard can hold hundreds. So there's something to think about. The display counts as one of the modules. So if you can save up for the Neptunes apex standard just so you have a lot of room to grow. I'll point out that there are tons of videos on how to set up an apex so you don't really need to do anything but watch the videos. It's fairly simple and extremely customizable. Apex recently remodeled their app and made it so much better. So the better overall one will probably Neptunes apex.
