If you register a ".ps" domain, it doesn't matter if you use MarkMonitor or Namecheap, they can't help you when the ongoing genocide results in the removal of Palestine as a country and ".ps" no longer is a valid country code top level domain.
Similarly, if you register a .us domain instead of a ".com", ".net", or ".org", MarkMonitor can't help you when GoDaddy inevitably screws up.
History has borne this out: .com domains are well-managed. ccTLDs like '.io', '.su', and '.fj' have all had significant security or availability issues because they're run by "eh, whoever the hell the country picks" with no standards.
Financially, a proper gTLD also can't raise prices unilaterally and weirdly, while if you pick a ccTLD, the country has free reign to arbitrarily change prices, delete your domain, take over your domain, etc etc.
Do not use a ccTLD.
