Unity Ads vs Ironsource for UA

I have a general question, and I couldn’t find a clear answer. Is there a significant difference between Unity Ads and IronSource from an ad network perspective, or do they use the same network, making it unnecessary to acquire users from both platforms?

For instance, would it be more effective to split a $2,000 budget equally between both platforms ($1,000 each), or would it be better to allocate the entire $2,000 to just one platform?

As an ad network for UA, Unity Ads and ironSource are completely separated.
It’s hard to say which one is better because its conditions are all different, but it might be worth trying them all out and keeping the ones that perform best.
