MG Recommendations?

Hey r/Gunpla,

As I'm rather close to finishing my HGUC Unicorn, I figured I would go ahead and order the next batch. I'm already set on getting a HGUC Gouf Custom but I'd like to get two MG's to last the rest of my summer.

I've been eyeing the F91 and Zeta 2.0 but I was curious if there were any good builds that I'm not considering. I'm a sucker for U.C leads but honestly, I'm open to any suggestions. Thanks in advance!
