One thing people should remember is that vram isn't everything when it comes to buying a GPU. It's certainly one of the most important things no doubt but it's not the only factor. Nvidia has always been stringent when it comes to vram. GTX 980 for example had 4GB of vram while consoles had 8GB of unified vram and so did the RX390.
But Nvidia always gave more features to counter such has Gsync which was better than Freesync at the time along with Gameworks and better tessellation.
But one key area that Nvidia has always been better with is driver support. While RX300 series was aging a bit better with games that required more vram, Radeon stopped supporting driver updates in June 2021. Meanwhile a GTX 970 had faster driver updates than 6900XT a few weeks ago and still bring supported. Not to mention the emulation compatibility issues with Radeon 7000 series GPUs that RTX 4000 series does not have.
It's why I said before that 4090 is the only gpu worth buying this generation. Spending money on Radeon with its lack of features and bad track record is a non option imo even if the vram looks great. But Nvidia has had ludicrous pricing on its 40 series gpus so outside of the 4090, they aren't worth getting rn either.
Imo the best course of option for someone worried about vram is either get a 4090 or wait till 4080 gets discounted or seeing if you can snag a 3090 for cheap or waiting for Blackwell. I wouldn't put faith back into Radeon after their recent incidents just yet.
