I used TeXtures extensively in the past under OS 9, and as of this version there is more than enough in the new version to get me to upgrade. The speed is excellent, flash mode works like a dream and I only miss the "go to error" and "go to line" features to be completely happy with it.

Those who have not tried this but who are in fact power users of TeX and need it to be fast, trouble-free, easy to install and user-oriented for large-scale production work should try this. Once it gets out of beta I expect it to be the TeX installation of choice for those who need all of the above features. (Not knocking the freeware implementations, but those who were power users of TeX in the past and who had gotten used to the feature set of TeXtures will know what I am talking about in terms of what it brings to the table.)
