It sounds to me as though you have been trying Linux distros. which are not suitable for you. Linux comes in many shapes and forms and have only one thing in common, being the kernel.
It is all too easy jump in to Linux wanting the Compiz Fusion 'Cube' without understanding how the rest of Linux works, I know I did the same way back with Ubuntu 6.10 only being impressed with the Cube which was then Beryl. Also when starting out with Linux you must forget Windows as Linux is a very different beast. The likes of YouTube only show the end result and not how it was achieved which in itself is frustrating.
Because Linux works differently to Windows makes it no less stable, in fact if anything Linux is more stable, with the kernel be constantly being updated.
On to distros. here are three easy to install and use (and stable)
Ubuntu 8.04.2 http://releases.ubuntu.com/hardy/
Linux Mint 5 http://www.linuxmint.com/rel_elyssa.php
Mandriva 2009 http://www.mandriva.com/en/download
How to install Ubuntu https://help.ubuntu.com/community/GraphicalInstall
How to install Linux Mint http://www.howtoforge.com/the-perfect-desktop-linux-mint-5-elyssa-r1
How to install Mandriva http://www.howtoforge.com/perfect_setup_mandriva_2006
Will we ever see a 100% stable release of Windows. I think not.

Edit :
You are using old Ubuntu distros. and the issues you mention no longer exist.
Here is how you enable Compiz Fusion (no longer Beryl) once Ubuntu 8.04.2 is installed and added any available updates via the Update Manager.
First you need to install the Graphics driver using the Hardware Manager to enable 3D acceleration system>administration>hardware manager, restart once driver is installed.
Once you have restarted Open a Terminal and submit the following commands :
sudo apt-get install compizconfig-settings-manager
sudo apt-get install emerald
Go to Desktop Settings Manager in preferences.
1. Click on general options at the top select the Desktop size tab, you will see that the Horizontal Virtual Size is 2 increase that to 4.
2. Go back to the Desktop Settings manager interface and select Desktop Cube and enable it.
3. Enable Rotate Cube.
4. Enable Expo.
5. Enable Viewport Switcher.
6. Enable Cube Reflection.
7. Enable Animations.
There are loads of tools and plugins which I have not mentioned above in the Desktop Settings Manager so you can customize your Desktop no end.
Also you will find the Emerald Theme Manager which is a must with Compiz Fusion as it enhances the experience immensely. See more here http://wiki.compiz-fusion.org/
Working with Ubuntu.
Much of the work in Ubuntu can be done via the Synaptic Package Manager without touching the Terminal. Here is the Official Ubuntu Synaptic Package Manager Documentation https://help.ubuntu.com/community/SynapticHowto
Should you need to use it. Here additionally is the Official Ubuntu Terminal Documentation https://help.ubuntu.com/community/UsingTheTerminal
