Not convinced by the video review page ...
To be fair Womble and TMPGEnc MPEG editor are not at all the same as the products they are reviewing. They simply convert stuff from one format to another and allow you to chop bits out as you do it. All the apps they are reviewing allow you to take clips of material and assemble complete videos including cuts, fading (and other transitions), special effects etc.
However, if they honestly rank Nero's buggy and clumsy effort higher than Vegas then either there is a hidden agenda or else the reviewer hasn't the faintest idea about video editing. Adobe Premier and Vegas Studio are ahead of most of those programs in terms of sheer power (not sure about 1 and 2 in the list as I haven't tried them but they are by reputable companies). OK they are harder to learn - precisely because they actually do something rather more complex than the other programs, and do it better.
Personally I think the review is based on ease of use more than anything else - a daft criteria for video editing which is inherantly complex if you want to do anything more than stick clips one after the other.
The other issue he doesn't address (at least in the bits I read) are about quality of output. Ulead come out at number 3, but my experience is that I have huge audio sync problems with the Ulead stuff when I have tried it.
Add to that there are none of the blockbuster applications there - Adobe Premier CS2, Vegas+DVD 6, Pinnacle, Canopus ... not to mention all the studio quality production apps. OK they are rather more expensive but Vegas+DVD would blow any of those products out of the water by many miles (to name 1).
