Jungls of Tambopata or Iquitos?

Travel Info
The travel agency is giving me the choice of these two places in the jungle. Opinion from peruvians? which is better?

Travel Tips

If I were to go, I would probably go to Tambopata. Iquitos can be too crowded and a bit on the dirty side. Manu reserve is very organised, there are lots of nice hotels and lodges, and it is more modern and better for tourists. If, by any chance, you are going to Cuzco, you can then fly Lan to Madre de Dios and from there go to the Manu reserve, the Tambopata region.
Others

I agree with umoanev, you should choose tambopata, you would like it very much.
