what's the difference between 4-cylinder and v6?
how come they're not called the same? i.e. v4 or 6-cylinder?
Most 4s are inline engines. Inline engines have one head, one manifold, and a simple cam drive. They have fewer areas for problems to occur and are usually easy to work on. 4 cylinder inlines do have an issue with harmonic vibration that is best corrected with balance shafts. Small 4 cylinder engines produce low torque and usually have to be rev'ed a little higher for power. Modern 4 cylinder engines are much better that the junk from the 70's.
V6's have 2 banks of cylinders in a v shape . There are more parts and depending on the car it can be more difficult to access parts during repairs. V6's produce more power at low RPMs and are smoother than 4 cylinder engines. The V angle is typically 60 or 90 degrees. A 60 degree engine may also have balance shafts to reduce vibration. 90 degree engines are likely V8 designs with 2 cylinders eliminated.
