Kickstarter has indeed a stronger brand and the quality of its projects is generally higher. It seems Indiegogo is always the fallback plan.

However, Indiegogo has a few strong points:
* It is very strong in internationalization. It supports many more currencies, languages and countries than Kickstarter. Kickstarter seems happy to be present mostly in Anglo-saxon countries
* Indiegogo is very strong in community (non-profit causes) and also in film projects. Additionally it has many health tech projects and finance projects that Kickstarter has not. When was last time that you saw an innovative finance project on Kickstarter?
* Indiegogo is growing faster than Kickstarter. Lately, Kickstarter has announced they will switch to a non-profit status and it's been a while they haven't announced new expansion while Indiegogo has fresh investment $$ and has announced new products
* Indiegogo has a staff that can help entrepreneurs and creatives. They will give you support before you launch and can give you advice to raise more. Kickstarter has very little support - apart from its shiny interface and automated interface.

At the end of the day, what matters is selecting the best platform that is best for your project. Conduct due diligence and see where the best performing projects are in your industry.
