Out of all the Gundams you know, which one do you think is the weakest??

In all of the Gundam shows?

For me, I think it'll be GP01 the non-upgraded mobile suit used by Kou Uraki, why? Too plain for me, unlike the other Gundams like RX-78, Strike Gundam and Impulse. They have that strong looks.

So out of curiousity, what's your opinion???
