Price being a non-factor, should I use the CoolerMaster v3 Vertical GPU mount over the LianLi 4.0 riser cable (in the LANCOOL 216)?

I bought both for a vertical GPU mount in the LANCOOL 216 and now I'm thinking about which one I should return. I'm leaning towards keeping the lianli riser just because it seems way easier to install and take out than the coolermaster kit. Is there anything else I should consider? Thoughts? I'm mounting a 4090 FE so the weight of the card is also a consideration.

I originally bought the coolermaster v3 so that I could try to squeeze some fans underneath my GPU vertical mount. Though with my MSI 670p motherboard one of the cables at the bottom (for the usb header I think) is blocking me from being able to mount the fan there so I gave up on it.
