I don't think it is a question of "good or bad" as it is a question of what you want to crimp. The Jameco page that you referenced, for example, shows lots of crimpers, but many are designed specifically for certain components. For example, Jameco#: 99442 can only be used for crimping the following connectors: 100765, 78318, 42649, 42729, 43377, 43369,or 104774.
The crimpers that Jameco (and other electronic parts stores) sells are all of good quality and will certainly last a lifetime of any hobbyist if they are treated with care and respect (i.e. don't use them to bang nails into walls, as plyers, etc.)
