Ah, well in that case.

Not even in my top 10 favorite Gundam. 

Visually and performance wise, it's a fancier, higher performance GM basically. Sure there's the 'Hammer' and Javelin but, meh. it's nothing special.

That said, it's historical importance is unquestionable. With no RX-78-2 and original series, to lay the foundation for both 'Gundam' class Mobile Suits, but for most the series's as a whole,  we wouldn't have our favorite Gundam or accompanying shows.
