Help choosing laptop

Hola, I need help choosing between

7i gen 9 NVIDIA® GeForce RTX™ 4090 Laptop GPU 16GB GDDR6

14th Generation Intel® Core™ i9-14900HX Processor (E-cores up to 4.10 GHz P-cores up to 5.80 GHz)

32 GB DDR5-5600MHz (SODIMM) - (2 x 16 GB)

2tb HDD

Or

9i gen 9 NVIDIA® GeForce RTX™ 4090 Laptop GPU 16GB GDDR6

14th Generation Intel® Core™ i9-14900HX Processor (E-cores up to 4.10 GHz P-cores up to 5.80 GHz)

64 GB DDR5-5600MHz (SODIMM, Over Clock) - (2 x 32 GB

2tb HDD

Price difference is around £500, I'm upgrading from a legion 7 r7 5800h 3080

I don't really use them portable, I leave them plugged in, the screen size and compactness work better for me than a desktop. Ideally looking for great performance and speed. Not sure if the difference between to two is noticeable or negligible.
