Are bigger engines more reliable?

Does v6 last longer than v8?
The car with the engine running at a lower RPM (the V8) to deliver the same HP output will outlast the V6 that runs at a higher RPM in terms of wear and tear, Outlast means probably a higher mileage for the V8 before a reconditioning is required.
