No, Zcash does NOT have good developers. They've been working on it since 2013 and they still launched version 1.0.0 with *totally broken* z transactions, the primary feature of their coin. This makes them either incompetent or dishonest, parading out a huge launch release with a complete absence of support for privacy. And they didn't fix it right in 1.0.1 or 1.0.2. Anyone who thinks they have a good development team is seriously deluded.
