Hows the Lenovo Legion 7 with 4090

Hi guys,

Looking to buy a high end gaming laptop.
This Lenovo Legion is in my budget -> https://www.lenovo.com/au/en/configurator/cto/index.html?bun…

I will be configuring it with a 4090. Costs roughly $4600.

What are people's opinion on this laptop and Lenovo in general?
Should get I get extended warranty for about $300 more?

Is there something better around this price range?

P.S. Has to be a laptop, not a desktop.

thanks!
