AppLovin is particularly well suited for gaming campaigns where it is really hard to reach users and you need formats like the rewarded video to keep users engaged with your ad. I would not recommend it for branding campaigns as their formats are more performance-focused and the inventory is expensive so unless you are trying to reach the desired CPA, it would not be worth it to pay that much for ad placement.
Unity is excellent for 2D and 3D games and educational experiences. It is well-suited for VR and AR development. It is also a great platform for mobile games. It is less-suited for non-game purposes (although it can certainly be used for those as well), or educational experiences. It is also less-suited for AR experiences that are highly complex, where you will probably want to write the native code in Android Studio or Xcode, as the case may be. It is theoretically less-suited for cases where performance is a huge concern as well, although, in my experience, performance has never been a problem.
Unity is a multiplatform game engine. It has more than 20 options for exporting your game, ranging from desktop, mobile, console, web and, lately, VR and AR. Unity was one of the first game engines able to export games playable on internet browsers and it helped to cement the World Wide Web as a place fit for gaming.
Unity has a very smooth learning curve for beginners. It is easy to start and soon you are seeing some tangible results of your efforts. The game engine has all sorts of helpers and shortcuts to facilitate some frequent tasks in game development.
Another of Unity's advantage is the access to Assets Store from within the game engine, allowing the user to import instantly objects, scripts and textures from the store into their projects. Such easy access to these elements from inside a project greatly enhances speed production and is particularly helpful to beginners.
AppLovin has been a great partner for us. We have used them through our DSP and gotten great results with them. Their focus is on monetizing publishers' inventory and they could put more resources into their standalone service as an SSP to make sure DSPs can consider them strategic partners for the long term.
It's actually incredibly easy to use given the complex tasks you have. Once you learn the various windows it becomes second nature. Compared to something like Blender (which I would probably rate as a 2 on usability), the learning curve of Unity is a breeze! The only improvements I can think of would be to streamline some common workflows so you don't have to dig through menus to find them.
AppLovin's support team is their weakest point. They are not very responsive and they tend to provide solutions that do not fix the problem. It seems like they will only be proactive if you are a very big client and by doing that they are preventing the rest of the client base from increasing spend on their platform and growing their accounts
I have not had to use Unity's support extensively. This is likely because there is so much documentation and so many classes available for free online. Due to this, there is little need for support. They were very responsive when I requested educational licensing. Setting it up and providing it all quickly.
Of all of the competitors above, AppLovin is the one that is more focused on gaming and that has a better pool of users in terms of conversion rate. While PubMatic and Magnate offer better solutions for CTV, AppLovin is better than InMobi and MoPub regarding in-app formats and inventory.
We love utilizing unreal engines but we seem to have a better use case for the architectural visualization side of things. This has given us the ability to find better more photo-realistic assets from not only the marketplace but 3rd party sites that have a unity bases file to work off of.
