Using Ionic will mainly come down to running some commands on the CLI to build, deploy, that kind of thing plus, possibly using some of the Ionic controls in your HTML.
They are very compatible with iOS but you should probably understand the difference between how Ionic compiles an app (essentially into a webview inside an app container) vs other options that result in native code (Xamarin for example).
Also, some other frameworks (ReactJS, Vue, etc) seem to have a performance advantage over Angular. I've built several apps using Angular 1 through4 now and have found the perfomance to be perfectly acceptable but not lightning fast.
The best tools are what you can wield and create results. Now I'm not an expert on Android Studio but I will share that I'm up to my neck using AS.
Let me share the story as much as I can due to client agreements. The client is one of my oldest and they tried outsourcing and they ended up with a collection of tools like Eclipse and all the other parts in order to make an Android developer system. So setting up is a PITR. After they called it quits with a few outsource places they can back to me with a problem/bug that needing fixing. For some reason I didn't get into the Eclipse setup they told me just wouldn't compile their project. Given the 30 day deadline I went back to AS and the project loaded and compiled. I was then able to address the issues.
So my thought is you have to choose the tools that work for you. In the case of Android work, AS is my go to solution since I need it to just work. I do not want to be mired in "production hell." (thanks Tesla.)
I've never been too fond of Android Studio. I use Visual Studio Code for anything Angular now and love it. But it really comes down to a couple of things: does the editor have the features I need to get the job done and do I like using it? If you say yes to both, use it.
For any Angular/Ionic project you can go into the root folder and run the command to send it to the browser, using either 'ionic cordova ...' or 'npm ....' for whichever way you initially set it up.
