Suggestions for Linux Distribution

I've been quite happy with my Steam Deck - both as a gaming console and as a secondary computer when it's docked, but for newer titles I picked up a Rog Zephyrus M16 (2023) last year.

Now that Windows is going off the deep end with AI, I'm looking to dual boot/trial Linux on this laptop with the goal to give Microsoft the boot.

It's a beefy laptop:

• 13th Gen i9-13900
• 32GB Memory
• NVIDIA GeForce RTX 4070
• 1TB NVMe (Windows)
• 2TB NVMe (Linux)

I added the second drive to avoid any issues with dual-booting with Grub/Windows Bootloader - instead making the Linux device the primary boot device and spamming Esc if I want to change to the Windows drive.

For distributions, I'm most familiar with Debian/Ubuntu - it's the daily driver for my work laptop, and the vast majority of my home lab VMs are Ubuntu. With the Steam Deck, I started to get more into Arch with the Steam Deck, and now it's the OS of choice for my HTPCs for simple streaming/Plex media player. I've also messed around with ZorinOS (basically a fancy skinned Ubuntu).

I need some advice on what to throw on this laptop - and some suggestions on how to squeeze the best performance out of this (Optimus vs. Proprietary NVIDIA vs. Open source drivers).
