With the advances in gaming on Linux in recent years, it is so tempting to switch full time. I would absolutely love to, but I am a Game Pass Ultimate subscriber and it is where I play a lot of my games on PC. I know you can use the cloud version, but I cannot stomach streaming games in their current state, so it is a no go. A large portion of my Steam library is compatible, but anytime I have done an install I end up giving in and going back to Windows for games.
If you choose Arch/Arch based, or choose to install one of its supported kernels, NTFS support is integrated into the mainline kernel since version 5.15

So you’d be able to use your already existing disk/partitions that have NTFS. Of course you’d still need to install the OS in another partition.
I tried to keep NTFS around when I switched, but ext4 is much better for spinning disks and support for whole disk encryption (LUKS) is also another pro that made me switch everything after a while
