Our 6 year old Grandson absolutely loves all LEGO building sets, but in particular Bionicles. As an observer, these hold up much better than the building sets with tiny figures and pieces. They do fall apart when in battle, but he enjoys them enough to put them back together again each time. And all LEGO sets have educational value if the child follows the directions and puts them together.
Overall, if you are looking to get an Agori, I would suggest Zesk, Tarduk or Metus. Get your Glatorian first, and then get your Agori. Wait for sales so you can get the best deal on the new sets. You can't really expect a lot out of a small set these days.
