Honestly, I feel like the PSP is the most underrated system of all time. Just browse through it's gaming library and you will find more unique and original title than what most systems offer up today. I owned both, but I owned upwards of 80 PSP games at one point, while my DS library toped out at ~10 titles. I actually enjoyed my 3DS way more than my DS. The DS was an amazing little machine but oh man most of its titles did not age well. So yeah, PSP by a mile for me
