So here's the thing, your list to vote on consists of all of my favorite incubators so you've been doing good research. My personal preference is in this order, NR360, IncuView, Brinsea, Hovabator. BUT I have varying reasons as to why they fall into those categories.
- Of the 3 types of styrofoam incubators I have experience with Hovabator was my favorite.
- NR360 has offered ease of use, good price point, and has remained reliable through MANY hatches over a couple of years for me.
- IncuView is a little bit touchier but it offers great flexibility in what you can hatch without needing to hand turn. It's also the easiest incubator I've ever cleaned.
- Brinsea is a great incubator though I did struggle with the humidity a bit more and I had to supply my own hygrometer because there isn't one built-in (I always use a secondary calibrated thermometer/hygrometer anyway) but I don't see a reason for the high price tag when I can get the same results from other incubators.
