This video is really good and it seems that the guy knows what he is doing. IMO you can get pretty good sound out of all of them. Which seems to be generally accepted. Of course there will always be people who for reason claim otherwise.
Most of the time I use Helix UI for editing patches, occasionally laptop if I have something major going on. I'm too lazy to hook up laptop and lifting it hurts my back. :)
Pop-up preview pops when you select item when using tablet and stays there for a while or until you tap the screen. This is really annoying. Tried to find a way to disable preview but didn't find. This makes this new interface worse than old one to me. Also above mentioned missing page markers are a drawback. Otherwise I like the new look.
Just bought Bogner Goldfinger combo, ouch. Just to play sometimes with tubes and liked too much that 60's gain channel. Most playing with Helix and if something leaves house for band fun, it will be Helix.
