Algo isn't that much better than any other VPN - arguably it's slightly better security wise, though I'd argue Wireguard tops it by far on cipher choices and security margins.
Ultimately VPNs just aren't for hiding anything that could cause you significant problems. If you want that, Tor, i2p, or piles of hacked boxes are your only options really if you must interact with the clearnet.
I don't know anyone working in the field who believes Wireguard is likely to be less secure than StrongSwan or OpenVPN, and Wireguard is something that gets talked about a lot.
It's early days for Wireguard, to be sure, but it's one of the most promising security projects there is right now.
I work in the field and anybody that says that a piece of software is secure before it has even had a security evaluation by a third party does not know what they are talking about.
I think what you have seen is security people saying that the design of Wireguard seems to be equal or better than other, current, options, that doesn't mean that the implementation is just yet.
