The latter is arguably the more important of the two.
I remember a scare some years back around a Monero developer that turned out to be a nothingburger, but it goes to show how important it is that the core development team is trustworthy, or at least sticks to their beliefs and don't capitulate to third-parties (whether public or private in nature).
Monero is the one coin I can confidently say I trust the core developers on, it's had a strong history of making the right decisions where it counts in my opinion (breaking ASICs w/the monero-classic situation, making the official client default to downloading the entire chain, etc)
