Guitar Strings

I have bought many different types of guitar strings over time, I get a new set about once a month.
These a few of them (well the packs anyway). The reason I kept the packets is so that I can remember the pack that I like best.
On the far left; I have bought them 5-6 times.
Middle left; 2 times
Middle Right; 1 time
Far Right; 3 Times
