BrowserStack vs Visual Studio

I am looking to purchase one of these tools for Mobile testing for my team. It should support Native, hybrid, and responsive app testing. It should also feature debugging, parallel execution, automation testing/easy integration with automation testing tools like Selenium, and the capability to provide availability of devices specifically for us to use at any time with good speed of performing all these activities.

I have already used Perfecto mobile, and Sauce Labs in my other projects before. I want to know how different or better is AWS Device farm in usage and how advantageous it would be for us to use it over other mentioned tools

The problem I have is whether to choose Android Studio or Visual Studio? I have to develop a simple app for a school project that can work on both iPhone and Android.

The most important factors for me are Android and iOS compatibility. Although note that i would like to become a Software Engineer when i finish my course. (I'd like to work for Apple, just saying!)

After that id like easy integration for Google Ads and such if i do develop another app that people actually use to support development. (I'd also like to stick with one easy programming language that's compatible with a wide variety of platforms since i'm a beginner and have only ever used Pascal)
