I believe it is all in the details- what type of adjustable system vs. what type of traditional pinning vs. who does the work. Let's say person X uses adjustable pins of a certain style while persons Y and Z both pin razors traditionally. Person X's system may be better than person Y's, but person Z might do better than both of the others. I think that the disadvantages of traditional pins stated here have been exaggerated and same for the advantages of adjustables. Really, when taken care of properly, you may never need to disassemble your razor fully to 'clean' and likewise you may never need to retighten a pin. Still it's all in the details- we all treat our razors differently.
