Hi, my experience when testing these programs is that you have to choose the interface depending on your skills, the level of customization you want and the need you feel for an alternative user experience to wm6. My best option if you stick to wm6 today screen would be rl-today inside of ultimatelaunch. If you do not need to customize much, htc home screen or spb pocket plus will do. The best option to replace wm6 interface would be spb mobileshell if you do not need to customize much and wad or wad 2 if you want to define your own flows to cover most of the usual navigation.

SPB MOBILE SHELL - A good all in one program for replacing today screen and access to most used programs. Very nice Skins available. Only combines with SPB Phoneweaver but not with Phonealarm (I like it more). I recommend it if you like SPB range of products and do not like to spend it to much time.

Mortbuttons: A great program, similar to spb mobile shell in terms of app navigation and app launcher (without the clock, weather, etc stuff). A good alternative to replace the cube. Much less resources consumed. Very, very easy to set up.

SPB POCKET PLUS - I would say it is more based on icons and today screen and plugins. It is more a utility to organize shortcuts than an alternative user interface. There are similar programs in other software houses like SPBH

THROTTLELAUNCHER - I find it more rigid than others with no real savings in performance.

WINTERFACE - I would put it together with throttlelauncher

RL TODAY It is a plug-in. You will take most of it if you are able to program tabs and shortcuts, wifi, bltooth... It is very good in rendering images but very slow if you want to support tabs. It has very advanced functionalities, it takes little space, it is quite complex and it is not so spread (some great people doing nice themes but less than with other apps). I have been using it a lot in combination with ultimatelauncher. It is the best option if you want to stick to wm6 today screen.

XIA: like RL Today, even more complex to understand and adapt if you want to (at least for me).

ULTIMATELAUNCH: Best cube I have used. Not the best rendering graphics and embedding plug-ins. It is a great balance between resources used and interface obtained. It takes longer time to customize than other icon based interfaces (the price of flexibility) but really a great cube

WAD 2: If your machine has 7 megs available it is a great great program !!!! It has a low-resource mode for machines below 64 megs of free RAM. Do not get scared about the 7 megs, it can replace many applications if you have the patiente to settle all functionalities it offers: HTC cube, ultimatelauncher, RL Today, RL Calendar, SetVolume, HTC Home, etc and even Wisbar Advance 3. WAD 2 is slow to load into memory but once there, I think is performs quite well. To set it up it is similar to Ultimatelaunch (every and each item has to be defined) but you can define whatever you want wm7-ish, xp, vista or whatever you feel like.

Wisbaradvance 3 is a great program since you can really customize the top bar with copy+paste accesible always and launcher icons and hiding the top and bottom bar.

Phonealmarm can also work as a basic htchome (see iwise). It is like rl-today or wad2: you get the best of it if you are willing to customize it yourself or find a theme that suits you.
