I would maintain that Pegasus is still a far more reliable source than Catalyst.
I disagree. I would say that the SR5 history and errata-flaws have shown that Pegasus is not an actual reliable source, since they partially make up their own errata instead. As such, they are completely unreliable as official source for the status of the english ruleset. It means you cannot ever depend on their releases in a rule debate, because it's impossible to tell whether something came from CGL or simply is their own decision, and they have shown to misunderstand at times.
