Which nvme setup is optimal?

I have an Asus z690-E Gaming Wifi motherboard with a Samsung 980 NVME drive, 1TB. 

When I use VMD/Intel RST drivers, I get the following benchmark results:

When I disable VMD/RST and use the Samsung NVME driver, I get these results:

As you can see, with the Samsung driver, my sequential R/W is worse; however my random R/W is better. 

Which configuration is optimal? As I understand it, better sequential R/W is good for large filesystem operations whereas good random R/W performance is better for smaller file ops.

As an aside, is it better to run my system with Intel VMD/RST enabled? This post seems to suggest so:

Thanks.
