Comparing cryptographic primitives by a Google publicity count is completely nonsensical. They offer disjunct applications: curve25519 is a mathematical group for protocols like Diffie-Hellman etc. while scrypt is a guaranteed to be slow hash function.
curve25519 was published by the renowned cryptographer Dan Bernstein in "Lecture Notes in Computer Science" ( http://link.springer.com/chapter/10.1007/11745853_14 ) and according to Google Scholar it has 114 citations. On its
Wikipedia page you could have found out that it extensively used by Apple in iOS: https://www.apple.com/iphone/business/docs/iOS_Security_Feb1... . It's probably going to be one of the major groups used for ECDH (elliptic curve Diffie-Hellman - the stuff you need for fast perfect forward secrecy) in TLS 1.3 and some even argue to ditch all the NIST curves in its favor.
I'd appreciate if you would do a minimum amount of research before you dismiss widely accepted cryptographic primitives just because you haven't heard of them before.
