MUI is still currently being developed. It is part of MOS and will be included with the OS4 distribution.
MagicWB is now past it's shelflife. How many people these days run 16 colour Workbenches?
MagicWB became dated for me once I installed OS3.5 and GlowIcons and got a Voodoo3. Suddenly hi-colour screens and multicolour icons without useing _any_ chipram, a world of difference.
MUI I still use as many programs need it. To be quite honest, I don't even give a thought out to it anymore. At one time eye candy was quite an important issue, but now it's what the app can do, rather than it looking good.
I used to have Birdie, VisualPrefs and MUI with quite flashy glyphs and colours, but now (after a system rebuild), plain old WB is good enough for me.
