I have researched the prepaids quite extensively and all do have something that is unique. If you are using a prepaid card for everyday use I would watch out for transaction fees and ATM fees. some cards do appear to look cheap but in reality i reckon can be quite costly.
Each individual will be different (needs) so look closely - I think prepaids are great but not all do agree. Hopefully if the forum monitors will allow, it will be great to hear which providers members would recommend and not recommend...
