Is it okay going for the 9070xt over the 5070ti in pcvr

I know that Nvidea is "better" for vr, but like it surely cant be that much better. I recently saw a video from Marakosot78, comparing the 2 and they were similar. I also know that the 9070xt has a low memory bandwidth of 640gb/s, compared to like 900gb/s on the 5070ti. Like i mean is that reallly important, I mean i would like playing on at least ultra or mostly godlike settings on VD on my quest 3s, so is the performance lost just like 5fps, or is it lots of micro stutters and more fps lost, shimmering etc. Also ive seen fsr 4, and it is impressive, I would say. So is the gap between dlss 4.5 and fsr 4 that big in vr, can you really notice the differnce or not? Also arent the 9070xt's encoders like just as good as nvideas, or is there still artifacts, etc?(also i have i7-14700, 32gb ram) (the price differnce is also like 350$ USD, 500$ AUD, 260Uk Pounds.
