It’s a good comparison between those two bikes. I debated too. I’ve gone with the Bird Aether9 Al in the end. I could pick and choose what I wanted and what really did it was having birds customer service.
I don’t have too much experience on different bikes. I’ve spec ed the Aether9 Al quite roudy super deluxe ultimate, 150 pike,etc..
Only been out a few times on it. And it feels very similar to the Am9 but a bit more lively. It’s still poppy but don’t think it’s as poppy as the Aether9c, probably because I’ve put heavier components on it and the frames a little bit heavier.
I debated on the Am9 or aether9 Al I’m glad went with the Aether9 Al.
Don’t need any more travel.
I would of liked to demo the XL Aether9 Al I when with the L Aether9. I feel Im in-between both sizes.
Good luck with your choice
