Would I rather have it than a 5.56? Only if the 5.56 was an SBR.
I think the main issue is that people are trying to put the 5.7 in situations it wasn't designed for. It wasn't MEANT to go through windshields. It was meant to go through body armor like cheese cloth and get the deed done from a FA SBR type weapon that was ultra-relaible and very portable. It does that in spades. Yeah, it sucks that us civvies have a hard time getting an FA/SBR'ed P90, but the PS90 is still pretty compact and full-auto is as much a liability as it as (arguably) an asset.
I think that it does what it was meant to do if you use the right ammo. I am surely not going to say it is the ultimate SD round, but I am also loath to dismiss it as ineffective when it mirrors the .223 in so many ways.
