I think iAd works best when it's possible to create a fresh immersive experience. If you're only using the platform to repurpose content a user could easily find elsewhere, it may not be worth their time or yours. If the product or message supports development of content that provides value, entertainment or otherwise, for a user, the platform offers ample opportunity
Vungle works well for branding and performance as video is a high impact format that and that has good CTRs and CVRs. However, for advertisers without a lot of budget, Vungle may not be a good option as the CPMs on the exchange are very high. For branding there are alternatives that have a more developed product, where video can be targeted near content the user may like, like Teads.
I would say is a standard video SSP. The reporting dashboard is well designed and easy to use and throttling options are standard. They seem to be confident about their inventory and they don't really evolve their product and add new betas or create audiences or do anything out of the ordinary.
Their support team is a bit slow. You have to re-send your email questions constantly because the first email never gets a reply. Their core business is still the ad network which does not involve a lot of human interaction so they are still working on how to evolve their account management team to be an exchange.
In some instances, we developed an experience for AdMob simultaneously with our iAd experience, working with both teams on a daily basis. While the Google team was skilled, receptive and helpful, Apple device functionality was broader and thus allowed for a little more imagination in bringing intuitive relevance to the creative content we developed
Vungle stands out as the only video only exchange. It is their main selling point and they have carved out a nice niche that differentiates them from the rest of SSPs. Their main competition, in my opinion, is Teads, which has focused the product more towards branding in order to monetize better for its publishers by getting higher bids.
