If you have not heard, the Android Market is now available to view on your desktop browser. I was pretty excited to see the features offered in the web version of the Android Market. However, much like many of you, I have grown comfortable using Appbrain for my Android app searching needs.
I’m not going to go in depth into Appbrain here. Here is a post to reference if you want a more detailed explanation of how Appbrain works. I will talk about the key differences between the 2 though.
Android Market key features
The  Android Market is the newest of the 2, so there is room for  improvement. There ARE a couple features that reign superior over  Appbrain. The first and most notable is the on click installation for  apps.
One click installations
The one click  feature works like magic. When you are logged into your Google account  on your computer, all you need to do to install an application is click  INSTALL. Within seconds you will see the little download arrow appear on  your Android phone or tablet.

Same layout
Both  the mobile application and the web version of the Android Market have  the same layout. This is very comforting to may people who like  familiarity. If you are use to using the Market on your device, using  the web version of the Market will be a very simple transition.
Tabs
When  you are looking at a specific application, there are tabs across the  top letting you easily jump to: permissions, reviews, whats new  (changlog) or the overview.

Appbrain key features
Appbrain  has had a little more time to hone in on some really useful features.  Many people, myself included, like to install apps just to see what they  do. Appbrain gives you a lot of sharing options the Android Market does  not.
Sharing apps
Aside from the basic  ways to share links to an application (email, Facebook, Twitter Buzz),  Appbrain gives you a few other ways to let people know about an app you  find.
- Being able to scan the QR code and easily download the app is great. Each application has a QR code to the Appbrain page.
 - Appbrain provides a link to email and another for foums that use BBCodes.
 - The third style link is HTML code. This code is for displaying a widget for the application on your webpage. I have used these before and they look and work great in an article talking about a specific application.
 

Syncing
Appnrain  offers an application in the Android Market. Once you sign in on both  Appbrain and the mobile app, you are ready to sync. It may take a minute  for the first sync. After, you will be able to see, from the website,  all of the applications installed on your device(s). If you need to  master clear your Android device, you can re-install apps easily.

Installing from the web
While  it is a couple more steps than using the Market, applications can be  installed right from Appbrain’s webpage. You simply pick which  application(s) you want to install and add them to the list of apps on  your device. Then, on next sync, you can install the apps on your  device.
While this seems like a lot more work, this method is a good way to batch install several apps at a time.
Sorting
Sort apps is a little different with Appbrain. You have filters for:
- Specific countries
 - Male or female users
 - Certain age ranges
 - Recommended for you
 
Being able to search differently than the Android Market allows, helps you discover more applications to better suite you.

Conclusion
While  the Android Market is shiny and new, my preference is still Appbrain. I  do not doubt the web version of the Market will improve over time.  Currently, features like the QR codes, syncing and the more advanced  search will keep me using Appbrain.
