I am not a technical guy. But I have read the whitepapers and found that the SONM has many advantages over GNT, as shown in this table.

As for the future of the investment, it is hard to say since there are whales in this market who may not care about the future.
Looks impressive, but at this stage, it's all fantasy. I could promise some super-ultra-bitcoin-and-ethereum-killer and try to collect funds with it. Actually developing it will be the hard part.
I'm not saying that the SONM guys are frauds or try to scam people, it's quite possible, that they believe with enough funding, they will be able to develop what they plan, but in my eyes, there is a big chance, that at some point, they and the community will realize that they bit off more than they could chew. Then what?
