If you were expecting a figure that was identical to the toon version of Jetfire, you may be disappointed. I don't know how much of the G1 history you know but in a nutshell:
Hasbro licenses a bunch of transformable robots to flesh out their new toyline from other Japanese toy companies. The Jetfire toy mold was licensed from a small toy company in Japan that was eventually acquired by Takara's rival Bandai. Since Robotech was going to be released in the US and if Takara wanted to use the cartoon in Japan, they had to change Jetfire's appearance to avoid any legal problems. The new character was called Skyfire. I don't know why he was named Skyfire and not Jetfire in the cartoon. Just remember that the Classics line is sort of a "if we made G1 Transformers today instead of 1984, this is what they would look like" series.
As for Classics Jetfire, I think he is the best figure in the line so far. The removable armor pieces allow for flexability in how you pose him—if you want a more G1 cartoonesque or a G1 toy look to him. Plus he is armed to the teeth
Ramjet is another good mold. An excellent homage to the G1 cartoon.
While Cliffjumper is a great repaint of BB, I do wish they remolded his head to be more show accurate.
