I often use UTM, for a number of reasons. First, its a bit easier to make note of than lat/long, the zones are a fair size (6 degrees in longitude), and it's really easy to calculate distances between points (basic trig). Also, the NTS maps are all in UTM coordinates, so it's easy to translate between the two.
That being said, there are other options you may want to look at. With grid systems (such as UTM), there is less error in position the smaller the zones. If your study area is small, you may want to look at a 3TM system or if your study crosses two UTM zones you may want to see if a 10TM system will work for you.
Basically the difference between 3TM, UTM (also known as 6TM) and 10TM are the width (longitude) of each zone: 3, 6, and 10 degrees, respectively.
Do a quick google search to see if any of these options may work for you.
