Byk I love ya man, but even I had to read that like 5 times

ok so you ordered samples of the Australian wombaroo diet and critter love ? Those are the two I saw samples for on that site.
Personally I'm not well versed in the Australian wombarroo diet, I looked it up on the pampered glider site. I know people used to use that diet, but the majority switched over to critter love original I think. There was a reason for the Critter love hpw coming about but for the life of me I don't remember what it was.
To me the Australian one seems more complicated from their feeding instructions. I would suggest you speak to Peggy directly she can tell you the differences better than anyone can.

Just shoot her a message she is very good about answering questions. She is probably more familiar with the australian diet and can explain it.
I do know Peggy has salads that go along with her diets, so you can use any fruit or veg off her salad recipes.

It seemed like her salads can go with the other diet too but I'm not sure on that one.
I've not fed any of the hpw's or wombaroo based diets, but if I had to choose one of those I'd go with critter loves I may just be more familiar with it than the other but it seems a lot more straight forward.
The main thing is don't switch back and forth a bunch trying to figure out what they like. Give the first sample a chance it can take a few days for gliders to eat new diets well. Going back and forth is hard on their digestive system.
I would start with which ever one you feel you can afford the most consistently, not just the staple part, but calculate in all the parts and ingredients of the entire meal ( fruits veg extra nectars what ever that specific diet includes. )
And consider availability, one of the items that is fed with the australian diet is out of stock on that site. I'm not sure where else it is sold, these are just a few things to consider when making your choice.
As far as what the gliders will eat well that depends on your gliders LOL I can tell you mine won't touch apples or grapes, yet lotssssssss of other gliders devour them.
