You're misrepresenting the idea behind this strategy: it's not "Selling a put because you "wouldn't mind" owning the stock" - it's "Selling a put because you "want to" own the stock but prefer to buy the dips; and selling the put pays you while you're waiting - even if the dip never comes."
There's only one scenario where you'd have been better off not using puts to buy the dip: that's if the stock gaps down further than your buy target/put exercise price by an amount greater than your put premium - a very small expected risk when compared to the expected rewards.
Selling a put because you "WANT TO" own a stock is even less consistent!
The worst sin in trading is not profiting when you have the right call. If your stock rallied 20% before your option expires, you will miss out on most of those gains (the whole reason for owning the stock).
If you are only looking to buy the stock cheaper then you have locked yourself into what that cheaper price may be. If the stock sells off further than what you have locked in, you have lost money.
This nuanced market timing is incredibly difficult and you aren't compensated for that.
Very few stock picker investors sell puts to acquire positions for that reason. Even the deep value guys who generally buy stocks and watch them fall before they turn around don't sell puts to "get a lower entry price."
Pretty much every new options trader has had the same thinking you have. And all the smart ones figure out that if you want to own a stock just buy the damn stock; don't sell puts or buy calls or do anything else unless your view has a volatility component that is enhanced by trading options.
