Google stated several times in the past that there is no bias in how they treat TLDs. All should be the same and I haven't seen any case studies ever proving either way.

If we take google words as a given :) then there is still the people bias. in the US people tend to trust more in .com .org .edu .gov .net It's partly because they use them for ages and that's the way they use the web. Partly because all the other domains which were cheaper were used for mostly fishy low quality websites as churn and burn projects.
In all the other countries people tend to prefer their own TLD with their own language. Like in Spain .es France .fr UK

So if you are after a domain for your money site or your PBN it's worth considering what's your users prefer and go after that.
