Isn't there a few different kinds of LTX's? Sometimes I think you have try different kinds, occasionally buying the most expensive, and perhaps even the cheapest (or ok, almost cheapest), in order to find what works best. Otherwise you will have to rely on antedotal evidence which will always conflict. There's no end of people have have glowing reports of cheap stuff--and glaring reviews of the same. Same for the expensive stuff, and for everything between.
