Bottom line: With naked long in options, you cannot be wrong and you have to be lucky in order to win. With underlying + protection OTM options, you can be wrong and not lucky and you can still win. Let me explain:
With naked long in options, you have to be not correct of the move but you have to be REALLY sure of the move and the move is going to be a big one in a relatively short time basically before the option expires, then it's worth it to save some cost upfront by investing in options because both the price move, delta and the volatility, IV is going to be larger than the time decay and you end up with higher profit but this is only when the price move is in your favour AND it's big, at least big enough to cover the option cost before the option expires. If either one falls short, then you will end up with the loss. So you basically need THREE things to be in your favour to win with naked long options, price move, magnitude of the move and dte.
Whereas with underlying + protective OTM options, as long as the price move is in your favour, you will make money because with the underlying delta being 1, it will always net you at least some profit even with the time decay because the hedging OTM option price will always be lower due to its delta being < 1 given the same volatility and when the volatility goes higher either with the price move going in your favour or not, it will actually play in your favour. If the volatility becomes larger when the price move is in your favour, then you will just net more of the profit with the protective options fast becoming worthless which you won't care at that moment, when the price move is not in the underlying's favour, the rising volatility will make the hedging option price rise faster to protect you against the losses on the underlying but what you need to remember is you need to close the underlying AND the hedging option at the same time when the hedging option price is increasing BEFORE the time decay sets in. That's the key. You have to cash in and lock in the losses when it's minimal or even reversed while the hedging option still has value. Do NOT wait!! The biggest mistake that traders make is wait thinking the price can reverse back. Don't ever think of the possibility of the "V-shape" curve that the price will come back up if you are long or the "reverse V-shape" curve that the price will go back down if you are short because you never know how much the price will reverse back. It may reverse back completely and go back to the direction of the original trade/investment or it may not and just taper off so you are still stuck with the losses on the underlying but the hedging option price is fast declining and expiring worthlessly because time decay has come back with a vengeance so you are stuck with double the loss, the loss on the underlying and on the hedging option. That's the worst predicament that a trader can be in and lose most of the money. Been there and done that many times and it's NOT fun. You need to think of protective OTM options as insurance policies with an adaptive expiration date. As soon as it thinks you don't need it anymore, it expires so you need to cash in when you need it the most. Don't wait!! The bottom line is saving your trade/investment NOW!!! If the price reverses back, that's for another trade another time. DON'T wait until the time decay sets in!! As long as you keep this in mind when you trade in the underlying with protective OTM options, you will be fine.
