Is Part 90 certification something an amateur radio operator should look for in a radio meant for amateur use?

I'm checking out cheap (~$100) mobile radios on Amazon, and often times there's a question asking about FFC Part 90 certification. As an amateur radio operator looking to use a radio for amateur/emergency uses, would I benefit from procuring a radio with Part 90 certifications, be hampered by it, or would it not apply? I suspect that Part 90 would hamper amateur use because of the mandatory lockout feature. For example, the Powerwerx DB-750X requires an extra kit to fully unlock the radios capabilities ($40 at this time).
