I fall into category 1). My Kemper is in a side rack that's just within arm's reach, but I have to spin the chair and reorient to work with the hardware UI, then back around to the PC monitor. It's not a huge inconvenience, just as the small screen and need for paging on the hardware UI isn't bad.
That said, I've been in the camp of not really needing the editor, but I can see significant usability improvements in the studio once I have it. This will eliminate the twisting the chair around 90 degrees, dealing with some paging because of the LCD screen size and other such things. Not the sort of thing I would have made a fuss about, but an improvement is an improvement and I'm happy to take it. So, while I could have lived without the editor, I'm very much looking forward to what the flow is like once I have it.
The value of the editor is soon realized when it comes to sound design and reamping.
