Frame up resto VS staged resto

Beguinning my restoration project, i am actually hesitant in that choice and i would to know by your experience what is the best choice regarding the datsun body particularity and my car rust area you can see it in my gallery (some of i already find...)

My first idea was to do a frame up restoration because i don't want to do an oversight on area that would be better to treat.

And don't want to see rust reappear under a beautiffull paint coat.

Last week a friend (bodyworker) saw the car and recommand me to do a staged restoration because for him, frame up restoration is lot of work for a not so best result compared to the staged methode, and take more time and money.

He is also against a total body stripping with a sand blast

give me your opinion and experiency
