I should point out I am a long time Line 6 user and I still use my Guitarport.
I wasn't keen on how Line 6 terminated some of the features, but that is life.
I still stand by my comments, Helix does come with patches which have been designed by Line 6 to sell the Helix. In my experience these patches are impressive. I was initially wowed.
As far as guitarists changing their gear, I think a lot of guys do it because they can (DIY bug) or they get bored with their gear, which isn't to say their amps initially sounded bad.
Also bear this in mind, I think a lot of guys like the lush sounds but in a very live room, it all can turn to mush.
