What are the pros/cons of using a 1.5 Tesla MRI machine vs. 3.0 Tesla MRI machine for imaging the brain, from both the patient's perspective and imaging perspective?

So... My Dr is having me go for an MRI of my brain & inner ear. It's being used to rule out a possible tumor which might be causing unilateral LOUD tinnitus in my right ear. Onset of this was very rapid and uncharacteristic of someone my age.
I spent quite a bit of time volunteering in a hospital whilst in undergrad and spent some time around the radiology suite there. At the time, 3T machines were just starting to be produced. From the glossy sales lit from the girls in skirts (a.k.a. sales reps) the images were amazing.
So, I'm wondering, for what I'm getting looked at, what's the difference (if any) from what I, as a patient, would experience and what imaging quality differences would there be (if any) between a 1.5T and 3.0T machine. I remember hearing that some places were getting crappier images from the 3.0T machines than they were with the 1.5T and that the ultra-slick images we were given by the salesholes were indeed taken with their 3.0T machines, but the settings used to make those images with those machines weren't practical for normal outpatient imagining use.
