your going to get a wide varation of opinions on which one is best but in my experience repairing them the most popular brand used in my area seems to be the moffet mounty. Second most popular brand would be princeton. Both units are very similar but the princeton appears to be the more expensive between the 2 parts wise. As for the manitou i wouldnt bother with that one, its overpriced for what you get and parts are hard to get sometimes.

As for dependability? Well either lift (moffet or princeton) will do fine for you IF you take care of it properly. Some of the most common issues i've come across with any of them is operator abuse conditions. Other than that i rarely deal with any breakdowns due to part failures. Note i did say rarely but dont be mislead by this because as with any equiptment failures do occur occasionally.
