I think it all depends on your needs, etc. I think every one of them has their pros and cons. We have an ExoTerra and we absolutely LOVE it. It holds temp/humidity uber-steady. On day 10 candling, everybody was alive and moving, 100%. Soooo we'll candle again at lockdown (one week from today!), and we'll see how it goes. I have "cheated" and spot-candled a couple of eggs in the interim here and there, and they are ALL viable so far. I have absolutely zero bad to say about this incubator and, so far, cannot say enough good about it. This is our first hatch & we're pleased with how it has gone thus far. I will have more to say (good or bad) once everybody is hatched and out and we know what kind of hatch percentage we get. We know they're all fertile because as of candling 4 days ago, all eggs have a viable chick in them!
However, I should add that we turn our eggs manually, and this unit does not come with an automatic turner. I have a full-time job but work from home so the eggs probably get turned about 6 times in a 24-hour period between myself and my husband (it's actually his bator... the hatching thing is actually his gig more than mine, though I'm having just much fun with it as he is hehehe). If you are a busy person and require an egg-turner, this is not the bator for you. If you can take a few minutes to turn before work, after work, and again before bed, I would highly recommend this unit.
