Hmmmh. I guess it doesn't really matter. I don't like credit card payments very much as we have a pretty good functioning European Direct Debit system in place in Europe. But Americans will never get it into their heads that there are working alternatives... It's more if you go for fixed or flexible funding as a campaign starter.

I do oppose Kickstarter more due to my experiences with it. Out of roughly 30-35 projects I supported about one third have failed to deliver at all, were endlessly delayed, canceled by the campaign starter in mid-financing (1 project) or changed focus on what the campaign is about (5 projects). So i didn't invest anymore in crowdfunding (with one exception on kickstarter + indiegogo each). I just let current projects run their course basically.

Note that failed, canceled or endlessly delayed projects give this sites a bad name (take the Jolla Tablet campaign for example but also Ouya console, Gamepop console, Erythia - Shattered Dreams, Haunts - The Manse Macabre, Wildman - An Evolutionary RPG, Body Scapes - Art Vs. Pornography, The Last Sleeper - Episode One or Unwritten - The Things Which Happened just to name a few which come to mind. Note also that a project which doesn't reach it's funding goal is not a failure in my eyes (Coldenlight, Hexit, Abandoned). The same goes for a project which delivers (IndieGO! console) or one which succeeeds in the second attempt (Days of Dawn). Some projects are very good (The Case Of Charles Dexter Ward based on the Howard Philips Lovecraft novel) but have been launched at the wrong time (mostly just bad luck, sometimes also poor research prior to the campaign) or meet strong competition.
