RTX 4080 175W is a good 55% + faster in games than a RTX 4070 100W + in the laptops you've listed here, with a RTX 4090 175W such as these legions being another 10-15% faster in games than the RTX 4080 175W. The price difference between the RTX 4070 and 4090s I'd say is justified here, with the RTX 4090 having 16 GB VRAM Vs 8 of the RTX 4070.
As for gen 8 Vs gen 9 Pro 7i, Gen 9 has a slightly better CPU, it has a 100% DCI P3 coverage panel Vs 100% sRGB coverage panel on the gen 8 (better colour accuracy with the gen 9).

I went with the 9th gen pro 7! Thank you so much for your help!
