I prefer the GP01Fb to the GP02.
Literal
I [topic-は] GP02 [than-より] GP01Fb [subject-が] like.
This is a reference to mecha designations from the Gundam franchise — GP01Fb (Full burnern) and GP02 are mobile suits from Mobile Suit Gundam 0083. The presence of Latin letters and digits in Japanese sentences is normal, especially for product/model names. The sentence structure is the standard より...が好き preference pattern.
