Yup, there's no doubt I'd heliski every season if I could afford it. Did it once, but probably won't again. You can match heli vertical by catskiing, though, if you go to the right operation.
I can't speak to whether you can match that vertical at Kicking Horse, for example (where I haven't skied, yet). But if you only have a week, rather than a season, at your disposal, catskiing in Interior BC is a better guarantee of untracked.
It's a good value, in my book, since it includes lodging, food, guiding and, of course, no lift ticket. I've done great resort trips at places like St Anton, Verbier, Jackson Hole and Alta, and have always gotten lucky with powder, but never consistently run after run for the whole trip like you get with a cat (or a heli, of course).
And remember, if you want to ski out of bounds safely at a resort, you've got to pay for guiding, schlep for your turns (which makes for fewer runs) and use lifts (can't remember if we skipped lines with guides at JH, think yes. In Europe you don't). Guiding don't come cheap, either. Nor does resort lodging or food. Catskiing costs more, but not as much as you'd think. And it's somewhere between a half and a third as expensive as heliskiing.
Another quick word about vertical. The week I heliskied in Canada, we ate up our guaranteed vertical by Thursday, which meant another two full days pay-as-you-go. I'd come half way across the world, not like I was gonna sit in the lodge, and the skiing was great. But I ended up spending like another 1500 euros to keep flying. Ouch.
