I hate most of these TLDs. All it does is allow more domains to be registered by spammers and scammers. It was enough that a company had to buy a .com, .net, .org and maybe a few country specific domains to protect their name, now we need to register almost a thousand or some scammer will sit on company-name.ninja just because they can?
To some extent, the existence of all these TLDs makes it more reasonable to just buy the one domain name you want and ignore the rest. If anyone actually tries to register your business name as a domain for the purposes of confusion, you can challenge the registration. But it no longer necessarily makes sense to proactively buy multiple domains.
