In my opinion, i feel that a good domain name that attracts people requires good researching.

It is always better when the domain name only consists out of 1 word and is singular.

You are right, it is not easy to register a good domain name, but you have to do some research and have the knowledge in the domain name industry.

Well the domain name should cover your trademark or service area.
