DR Strings NMCE-10 Medium (Multi Color)

I'm a beginner, so I will not comment on the sound or feel of these strings. Neither do I have much to compare with regarding how well they stay in tune. They seem to work well enough, except for the coating on the high E and B strings - this started peeling off where I'm picking and strumming. My pick is a .73 Tortex, so nothing crazy there. The high E string is also stripped of coating on every fret from 1 to 12. I have had these on the guitar for about three weeks, and used the guitar maybe 20 minutes per day on average. The lower three strings still look more or less like new, though.

Have ordered some other strings (different type and brand) to replace them with.

These strings are very interesting to play with the Rocksmith game (the string colors match the game), but also for the learners to use, and they look cool! But that is it.
Unfortunately, the colors wear out quickly over the frets after continued use.
And I have the impression that the sound is not very alive, compared to regular nickel wound strings. I also find them trickier to tune and it seems not holding long, need to retunning every now and then.
