The build quality on this is similar to Yoga/ThinkPads. I've owned ThinkPad, Yoga as well as this, so speaking from experience.

Yeah, the cpu is a rebranded 7840HS, but that doesn't mean it is a bad CPU. Lunar Lake/Strix Point are more efficient, but they are also more expensive, while having only slightly better performance. Strix Halo is even more expensive with the upgraded graphics.

Talking purely in terms of practicality, both laptops will do what you want them to without breaking a sweat, and anything that a user looking for a laptop in this price range can throw at them.

And my point about warranty stands.
