Two Airbrushes

I already knew from this forum that iwata and tamiya is made from one manufacturer in japan. I would like to inquire if which one is better since i want to acquire the iwata HP-BS or tamiya HG-SF.

I think the better choice is the hp-bs. parts are cheaper, needle is wider (easier to clean), more parts availibility, and since iwata has been around longer than tamiya (airbrushes, at least) I would think they is better. Thats my $2.
