I feel like anything that is not either ".com", your local country domain (".fr", ".co.uk"...), ".org" or a very trendy domain like ".io" is not really a great choice unless it combines well with the rest of the domain name to turn into your or your company/product's name. Most "non-standard" domains will look shady to inexperienced users, unless your target audience is niche / tech and most importantly not a customer, in which case they probably won't care about the domain in the first place.
Personally I look at websites this way, if it's ".com", ".org", or "." it's probably a business or organization, if it's ".io" it's probably a young startup, if it's ".net" it's probably old and not up to date/relevant, and if it's anything else it's either a blog or a scam.
