If your buying decision is based on whether you will resell it, then why spend so much? You will definitely loose some money because you won't be able to sell the Gibson USA LP at the price you bought it (Unless you have the skills of a used car salesman)
How much will you spend "extra" for that Gibson USA? Airfare? Taxes? "Thank you tip"?
If you are at a point where you can determine your tone and playability on woods, frets, neck type, electronics, then a custom LP might be the way to go.
If you are going are going to just get tired of the guitar and resell it afterwards, then there is no question to ask.
Each person here will give different opinions (and personal biases) on what option they will choose when something like this presents itself. I envy you that you can have this choice.
