First the sound is radically different. These strings provide a certain color that is found rarely with other brands. I used before Fender strings with a special coating that gave them a friendly tone but that is nothing compared to Elixir.
Then we note of course that set of strings is more expensive than most offered in the market but note that these strings last much longer. On the one hand the oxidation appears only very late (even with regular use) and secondly we see that they sound all their own can be heard for several months which is not the case with the game usual.
In short I recommend this product! To my taste this is the best that exists to this day.
