All issue trackers can be placed on a spectrum: one end is occupied by very fast and very simple apps, another by complex and flexible ones. Fast ones win in the ease of creation of an issue (just type and hit enter), and generally feel more sexy and attractive, but complex ones can be set up to the exact workflow you need. For example, Google tasks or now-dead service do.com by Salesforce clearly belong to 'easy' end, and software like Redmine to 'complex' (though it can be made to look rather attractive by the use of skins). For us, we're sticking to redmine, because it is good and very extendable by the use of plugins. We've found that ease of use does not cover for the reduced flexibility.
