Double buffering in itself never removes screen tearing, but V-syncing always has the purpose of removing screen tearing. If double buffering removes screen tearing then it's understood that some vertical syncing is also taking place.

One reason to use a CRT is to avoid the small lag/delay introduced by flat screens due to how they work. This delay is only the duration of a single image frame so it's pretty negligible.
