It's decent competition for sure. Significantly higher spec versus Deck on paper but they are pushing the envelope for powerful x86 machines in this form factor. Seems like you can melt the battery extremely quickly if you try, since the Ally is a 1080p device. Seen benches around the 50 minute mark. Really no different than running Deck for 90 minutes playing Elden Ring at 800p.

Ally works with Asus' proprietary eGPU enclosure, theoretically can expand horsepower even more. Again though only so much you can do with the form factor. I get using a dock but dedicated accessories seem like they'd provide diminishing returns versus conventional PC hardware. Especially at the price point. Base model Deck blows this thing out of the water value-wise.
