No, not really. Honestly. I can't speak for
@SuncrestReef but I believe we both try and answer these questions objectively and fairly. We also call out that we are Apex users and may be biased. I believe that lets you know as you go through the answers.
I sort of see it like this. Both Apex and GHL are the main players in the market today. Neptune you probably have figured out is the two ton heavy thing in the US. GHL is second fiddle. It doesn't mean one is better than the other as they both have their respected places.
Here is an example. Let us say your question was different instead of a controller you are asking which automation testing unit would we recommend. My first reply would be this:
@Shawn_epicurious do you already own a controller?
If you replied yes, Apex, then my reply would be for you to consider the trident. Why? Because you are already invested in the controller so it would be a lower cost entry point. I would then tell you my experience with it, the pro, the cons, etc. It uses reagents which some hate, others don't care, and some like.
On the other hand if your reply was no, you don't have one. Then I would reply differently. Apex has the trident, here is what it does, pros, cons, etc. Then I would say GHL is introducing their system and it they are using probes with reference fluids. I'd give you the link and say if you are shopping for controllers this is something to consider.
Then I would also include a third choice which is the Reef Bot. It is a reagent / test kit based system that automates the manual steps. There is a hobbyist list of which test kits work the and companies like Tropic Marin are packing up a specific test just for it due to its popularity while saving the hobbyist money. I think that is cool and have since moved from Two Part dosing (Alk/Cal) to their DIY tropic marin all for reef because of their support of our hobby.
So you see while I am an Neptune customer I can also step back and answer a question somewhat objectively. Hopefully this makes sense. Both are good and I don't think you can go wrong with either.
Note: I've not used GHL products but do like their aesthetics and build quality. I like Neptunes user interface and wizards to control. Probably the best selling feature along is the heatbeat monitor. That alone is worth the price which more or less lets Fusion application (web / cloud portal) ping your controller and if it is offline will email you. That could mean power failure (major) or network issue (minor). So you can act on it.
If you are a coder - I think you said a CPA - Reef Angel is going to require some basic understanding of code. The forums they have are very helpful and you will be able to get it going with little effort. They also have a wizard to get you going. But things like tidals, geo location, and more will require some work.
Hope this helps - have a great evening. And welcome to the controller club. Not mandatory but helpful. And as you grow so do the options to grow such as dosing and automatic water changes to name two.
