I think it really depends on your foot and running gait. If you tend to pronate a bit, I would suggest a shoe with some support such as the Montrail Mountain Masochist. They also have a "waterproof version" (the GTX I believe, but its a trail runner so its not really going to be very waterproof) and a model with a bit of ankle protection. If you have a lower volume foot, la sportiva shoes will probably fit you better as the toe box is typically narrower.
I've run quite a few ultras and have found that Montrail shoes tend to fit my foot better than other brands (I need a wider toe box). La Sportiva, Innov-8, and Salomon also make great shoes, but I will say that many of the Innov-8 models are more minimalist with a low-heel drop which may not be what you are looking for (based on your "bomber trail runner" headline) as they will feel much more slipper-like without much support. I've run a bunch in the Brooks Cascadia and like it a lot. The mountain masochist is a bit lighter though and really fits my foot, so I switched to that one. Lastly, depending on the amount of running you are doing, it is probably a bit unrealistic to expect trail runners to last a year. I seem to go through shoes every couple months (but I run a lot, so it just depends).
