MR5200: USB or Ethernet, will used it mostly for DotA 2, since it is advertised to have less latency

[arwinrt]

So my ISP is offering the new Nighthawk M5 MR5200, I just can't get it since our area is on lockdown due to the outbreak.

I just want to make sure that the attached image is true, because from what I know, internet connection from an Ethernet cable is as of now the fastest of all, but in the website, using it by USB (Tethering) is the way .

I will use it mostly for playing an online game, currently my HUAWEI Bolt Hotspot E5788, by USB (Tethering NDIS), from the same ISP is giving me around 120 MS, will try this new product from NETGEAR and my hopes are high that it will significantly lessen my latency while playing online games.

Please, I need some insights from these connections.

PS: I can't apply for a wired internet (DSL at least) or Fibre internet in my area right now since I'm only living on apartment. I'm only here in Kuwait for work. 

Thanks for reading.
