Both are great products but I like more the omni nest, has better view and Fire Ants look awesome in them.

Bump. I am also curious about this and if one has an 'ant'vantage over the other. I think I'm going to get the omni nest large because it comes with an outworld and I like the "view from any side" setup. Plus they just look great!

Yeah it is probably more of a personal preference than anything. With the Hybrid, we hoped to remedy some of the little problems or issues that antkeepers have to deal with. For example, it is easier to deal with nest hydration with the Hybrid than the Omni. There is a built-in option for heating the nest. You can separate the hydration system from the nest section making it easier to clean and it has better connectability to test tubes and tubing.

You can't beat the viewability of the Omni though! Omni also comes with its own out world as has been mentioned and it just looks cool too

Up to you. I'm sure you'll be happy with either one.
