First, beating the horse, if one is looking to capitalize on underling movement one should be buying options, not selling them, (where 'buying' may be more nuanced than just a single leg +C, as discussed ad nauseam in previous posts).
That out of the way, the major benefit of the naked -P vs a covered call (100 shares + -C) is the capital requirement. Depending on one's margin requirements there may be an opportunity to open multiple -P's for the same capital as one covered call position. In that case yes, a capital-normalized position of -P's may well return more than a CC, though it very much depends on the CC's strike price (A DOTM CC has the upside potential to far exceed the return of even many -P's.). In this comparison the risk is generally going to be higher on the multiple -P's, but its not a straight apples-to-apples risk overlay as it is very dependent on strikes and expirys.
If we're not normalizing capital and are instead just comparing one OTM -P to one CC, the covered call will always return more than the -P if the strike of the CC is ~equal or above the strike of the -P (in other words, that's starting with an ITM CC). That additional return of course comes with additional downside risk on the CC (for any strike above the -P), so again proper analysis is of course necessary.
