2) it is not superior? Well as a web developer I look a lot specifically at implementations and it is my personal belief (which I can back up but don't want to flame here) that Voyager's EMCA-Script implementation is far superior.. If I run all three browsers simultaneously I still also get a superior rendering of a page (barring any CSS or course) with Voyager..
There are two problems with Voyager:
1) it does not have clipboard support (you cannot copy text from web pages easily)
2) it does not work very well with MUI4 (though, IBrowse developers are not better there either...)
I liked Voyager very much and it was always very fast browser also. Its demo version (for 68k) was also very unstable which contributed to its reputation.
