What are the performance based advantages of ReactJS when compared to the Angular2?

You can check out this comparison of the two through which ReactJS is rendered out as the easiest to use over AngularJS. But I'd like to also stress that this is purely opinionated and this might change depending on the application being developed and its context.
For further information, you can refer this.

Right now, I mean today:
ReactJS is mature (version 15.x)
whereas Angular2 is in RC5 (not mature)
So:
React is a today or middle term best bet in term of performance (rendering, bundle size etc...)
Angular2 (if it does what it is promised to do later!) should be a long term bet.

I wonder if writing react components as HTML first can be a good idea to plan the project or it is actually a bad idea and time consuming??
Though, this is primarily opinion based question, the react documentation simply states to follow these rules:
Start With A Mock
Break The UI Into A Component Hierarchy
Build A Static Version in React
Identify The Minimal (but complete) Representation Of UI State
Identify Where Your State Should Live
Add Inverse Data Flow
See Thinking in React for more info.

React with JavaScript or TypeScript?
which is best if typescript is please explain why it is.
This will depend on the size and type of the project. If a small project is developed by, for example, only one developer is sufficient for JS, if one is a large enterprise solution, then it is a better typecript.
The TypeScrip main features:
optional static typing (the key here is optional)
type Inference, which gives some of the benefits of types
access to ES6 and ES7 features
the ability to compile down to a version of JavaScript that runs on all browsers

What is the preferred pattern for creating a repeater in ng2? I was thinking that I might do this with NgFor but NgFor is deprecated according to angular.io: https://angular.io/api/common/NgFor/. However, the same page on angular.io doesn't state the repeater pattern that should be used as an alternative. Can anyone here provide some insight on the latest patterns being used to implement repeaters in ng2 apps?
In most cases, you want to use the short-cut version: *ngFor. Behind the scenes, this is implemented as ngForOf. If you stick to the short-cut version, you don't have to worry about the "behind the scenes" changes.

I am starting a new Android app, and I would like to know what should be the best server-side stack that I could use.
I heard some about MeanIO, MeanJS, Cleverstack, Generator Angular Fullstack.
Which of these suggestions should be the best? Is there another one that is not on the list that would be even more interesting?
If I am correct in saying it depends in what you're doing and trying to focus on. If you wish to also build a web-based front-end it's probably necessary to include AngularJS. If you aren't planning on doing that you could probably cut out the need for Angular.
I imagine the MEAN stack (https://github.com/meanjs/mean) would be enough for your Node.JS server. I doubt you will need to use Angular for an android app so you will be more focused upon the Express+Node+Mongodb portions.

This will be a bit strange question, but..
I am planning to use jQuery/knockout to write a dynamic custom wizard
which will depending on different scenarios will load different templates/UI logic to the user.
Question.
Should I take into consideration memory usage in this case? or should I manually unload/clean up/save to the server pieces of UI which is not in use??
PS. Current version of wizard will have 5-7 steps.
You should write your app the best you can functionally and then determine if memory is even an issue. If it is, then you can take steps to reduce it's memory footprint but odds are you'll be fine. For instance, go look at what a site like Facebook's memory usage, a site that everyone and their grandmother uses.
