The CVs all do their best and sound like they're having a blast voicing their characters, and I feel that it's very well represented in the final episode. The finale is definitely a twist that I wasn't expecting, and I will refrain from spoiling it entirely since it's something worth experiencing.
The music is fantastic, Angel Rock and Roll is easily the best OP right next to the original Galaxy Bang Bang. The OST is miles better than last season and fits each scene perfectly. You can feel that the writers were determined to give GA a proper sendoff, and as such they write some of the best episodes of GA to date: Ordinary Extraordinary Chocolates, Commander Invasion Flavored Spice, Soup That Has Simmered Extra Long, Go Ahead Rice Cooker, Memory-Full Sukiyaki, and just so many more. There is hardly any "okay" episode, because they all range from good to amazing!
Like someone mentioned here, it's highly recommended that you watch the other three seasons before touching S4/X since you jump right in with hardly any introductions like with Z and A.
The comedy is easily the strongest it's ever been. Just about every episode is guaranteed to get a laugh or chuckle out of someone. With the addition of Chitose Karasuma, there's a fresh formula that provides a gateway for so many jokes and when there's a Chitose centric episode they make sure to utilize her insecurities and mixed personalities fully. Sadly Chitose only has about 5/26 (yikes) episodes where she's a main character, she mostly gets the Twin Star Troupe treatment to where she's disregarded until they need a short gag.
But despite that, everyone is in top form in their own way. Milfeulle gets targeted by a hitman but always escapes death, Ranpha is the main character of a romcom bishoujo anime, Vanilla stalks someone and turns them into a fish, Mint almost murders her teammates (and kill herself) because they burnt her precious animal costume collection, Forte destroys an entire planet, flashes her womanly features to everyone because they though she was a man, and she also turns into a spider, lady... thing...? after she swallowed a spider avenging his father after she stepped on him. Those are real sentences I've written.
Galaxy Angel X is pure insanity that must be watched. Please enjoy GA~
