Think you still will be using scihub. Unless I am missing something (or only correct inside China or need an account) it seems like "just another" aggregator (which is useful, don't get me wrong) and doesn't really make anything available that wasn't already open access. Although being able to focus on some Chinese output, like thesis, is nice and things like that might get missed by other services (idk)

I was pleasantly surprised that the creator of scihub is this weird Stalinist graduate student lol
