Yes, we would use Kickstarter again. It drove a lot of our traffic and the community of backers seems to have a unique cohesion. People on KS know what they are getting in to, and are there to help. It has it's downsides, but in my opinion the pros outweigh the cons.

I think each company is different though, and you have to consider your strengths, as in do you have a strong online acquisition strategy/team, in which case a campaign on your own site may make more sense.

Now that our campaign is over we use Celery for pre-orders on nebia.com
