From my experience with albigs both work great.
Its not just the animal type thats better or worse, its the husbandry that allows the lizard to use that prey item. Rodents take slightly more suitable conditions to digest at the same rate (birds usually digest a bit faster).
I have good results with both, but someone who breeds them such as FR and someone who has bred them many times also (Rob Faust) use rodents. This is only the beginning of the list of those who have used rodents only.
I do like to use birds more often but thats my personal preference, and a less expensive one in most cases Lb for lb in prey items. Ive had some albigs that preferred birds only for periods of time, and some rodents only for periods of time.
I know they grow fast on both.
The smell is different when it comes out the other end before they get used to them, some take a while to get used to birds. Also day old peeps come out the other alot end smellier than 3-5 day old peeps, or older yet. I wish I could still get 5 plus day old or older big peeps.
