I prefer Cat Skiing. There's never down time because of weather when the heli can't fly, it's cheaper, plus on I'd say on average the runs are a little better (not as mellow as heli-skiing). Of course everything varies from company to company, but that's from my experiences, and a few friends of mine who have done both share the same thoughts.
Heli-skiing is for rich folks that want to go ride untracked powder on low angle slopes with no features.
If you want the ultimate experience you get 'heli assisted backcountry' which basically means have a chopper drop your crew off in a remote location and pick you up later in the day.
Of course the experience of flying in a helicopter can't really be beat... but I'm looking to go shred, not for a touristic ride.
The cheapest Heli ops start at about $700/day and go upwards from there (the skies the limit... like $10,000 per day if you really want). Most don't do single day trips, but there are some that do.
