I currently use 10.04LTS and I use a dual-boot laptop to "test" out what the Ubuntu versions look like. When I see that the newest version works and I can tweak it enough to switch over to it, then I will upgrade my default 10.04LTS desktop to it. Right now running 12.04LTS Beta [April-12th download with the login of "GNOME Classic" seems to work better than 11.10's version. There is an issue on the very limited theme choices and their tweaking options. 10.04 has many, many more available. But if I have to live with what there is, then I will have to do so. I hate Unity with a real passion. I do not want my desktop to act like a tablet.
The LO included with the current Beta was 3.5.1.2, which it the "final version" of 3.5.1, I believe. I will be removing that in favor of 3.4.6, which is what I run on my desktop.
I still would prefer the options and tweaks that you get with 10.04, but that is going to be really too out-of-date soon. As it stands, there are many packages that 10.04 does update, but not with the most current line. Thunderbird is still being updated, but using the 3.x line instead of going to 11.x. I installed TB 11.x myself and created a launcher for it. That way, when there is an update for TB with 10.04, it will not overwrite the "proper" TB folders from 11.x back to 3.x.x.
But, all in all, 12.04 LTS seems to be better for those who want GNOME's 2.x look and feel over GNOME 3 and Unity's look and feel.
I did not like having Writer, Calc, and the other LO icons show up on the limited left "panel" space that Unity uses. I display Writer and the "all module" launch icons on my top panel and my desktop screen. Did not need Draw or the Presentation icons shown.
Well, that is my opinion.
But at least Ubuntu is making it easier for us GNOME 2.x people.
