The 'most efficient' method is by default the one that will cost you the least time (and make you reach your goal the fastest way) in the long run. Whatever your preferences are, there's always one method that's the absolute fastest, and it's your choice whether you want to use it or not. The efficiency of various methods depends on the money/hour you can make, so usually this is expressed as 'if you make 360k/hour or more, this method is the most efficient for you'. There is no such thing as opinion about efficiency. A method is either efficient or not, and if you want to use it or not is completely up to you. If you value things such as 'fun' (boring mortals, fun's a waste of time ) higher than being efficient, then by all means go ahead and do whatever you want. Just realize you are spending more time on whatever you want to achieve than you would have spent using an efficient method.
