When I print them I cannot tell which are which. In retrospect, it WAS too much work.
I ask this in a sense of inquisitiveness, what made you carry on for all those years, did you not discern a difference in the first place ? I have often wondered whether sometimes we get carried along on a wave of trying to do something different or because others have tried it. I am not saying that all developers are the same, clearly they are not but if the benefits are not that great for the individual and finished results are not a 'revelation', as you say, why carry on. It all boils down to personal preference and whether the results are what suits your style of image making.
