That's a tough one. I find that Kalk is the easiest and likely the most cost-effective, to a point. That point will be when dosing Kalk can no longer keep up with your demand. You can only add so much and that will be determined, ultimately, by your evaporation rate. I use a dual chamber calcium reactor. If things go out of whack I adust with 2 part. Once the reactor is dialed in, it is pretty darn easy and I can easily adjust as demand increases. It is really subjective though. All will work and I have used all or some combination of them. Some good fodder provided by BRS in case you have not seen them...

Depends on consumption. I started out on two part which was very stable and got tired of mixing every week. Yes I went to larger containers but that just delayed it. At first I had some issues with consistency but a food scale fixed that. I moved to a carx to avoid mixing 2 part. Now I’m to the point I want to supplement with carx with two part. Keep in mind costs. Carx: reactor, media, co2, regulator, dosing pump. 2part: mix, containers, dosing pumps. I’ve seen many people switch back and forth. You can be stable each way. Imo people that switch to carx typically want a new toy to play with. If you are focused on cost go 2 part. Otherwise enjoy a new toy.

None of them are "easy" in the sense that you don't need to pay attention nor know what it going on. Neither of them are hard to learn.

I would base this off of the typical coral that you want to keep as well as how long you might want to be in the hobby. If you are going to be a huge stony guy for a decade, then a CaRx might be a good idea. Mixed reef, then kalk or two part can be great.
