I don't want to use Ubuntu Gnome Remix because I think it is kind of "incomplete". I prefer to install Gnome Shell on Ubuntu 12.10. I've searched the net for instructions on how to do it and found two different ways:

1. Simply search for Gnome Shell on Ubuntu Software Center and install it.

2. Follow the instructions from this WebUpd8's post.

Now, my doubt is: what is the differecen between the two methods? Which is the correct way to do it? Does the first one lack features? If so, which ones? Is the second one better? Why? Is there a third and better method I haven't found?

By the way, I have already tried (for testing purposes) the second method (WebUpd8's) and noticed that it installed some apps I really don't want to have, such as AbiWord and Gnumeric, because they are Gnome's default applications. So, "if" the second method is the way to go, I can certainly remove those apps manually, after installation, with no worries, right?

Thank you very much for your attention.
