Welcome to Gaia! ::

Best: Florina (FE7) takes the cake for me. Available from an early point in the game, gets surprisingly good Str to rival her sister Farina, gets decent defenses to rival her more well-rounded sister Fiora, and dodges everything. By the end of the game she barely ever gets hurt for me. If I played FE8 more, I might pick Vanessa over her (the last time I fully completed FE8 Vanessa's Str growth hated me and she had maybe 12 Str at 20/20... >.o) but as it is, Florina all the way. Plus, she's adorable with Hector. Awwww

Worst: Again, lack of FE experience, but I'll have to go with Syrene solely because I haven't obtained Yuuno before. Comes too late in the game for me to want to utilize her, and she doesn't have good enough growths to merit babying her EXP. Sorry, hon. Your design is nice but you just aren't a very good character.

I love flying units, though. Pegs and archers are my favorites~

Best: FE 7's Florina.
Worst: FE 8's Syrene.

Best: Battle Before Dawn (E26/H28, I believe)

I feel like it’s a really fun and engaging chapter. There are a number of things you need to try and accomplish, you have to split you party in two (well, I suppose you don’t HAVE to, but it’s strongly encouraged), it’s a fog of war which always changes things up, and you always have the option of pushing yourself to try and kill Ursula. Fun stuff.

Worst: Four-Fanged Offense (Lloyd version) (E23-A/H24-A)

It was hard to think of a worst chapter, actually. But, uh, getting the Lloyd version of Four-Fanged Offense means you’re stuck with Wallace rather than Geitz. It also likely means your Lords are underleveled. Both of those observations associated with this chapter are bad things.

Best: 19xx. Call me crazy, but I found that both the challenge getting here and the backstory made this a chapter worth noting. How many people would even know to get Nils to level 7 in Lyn mode? Plus this is a gaiden to a gaiden, so...

Worst: E29x (forgot the Hector mode one). A "battle preparations" chapter where all you do is go shopping and get Karla. The game is offering you an advantage you don't really need - and it didn't necessarily need this chapter to give you Karla either. Basically, it's pretty much a handout with nothing much to offer. I know some people will of course disagree, but I never really liked this chapter regardless.

Best: FE9 Ranulf

Worst: FE9 Ulki. I always ended up using Janaff over him

Best: Volug (Though, I am on the verge of switching to Ranulf)
Worst: Kyza

Best: Volug (FE10 Ulki is RIGHT behind him, though)

It’s a tight race between Volug and FE10 Ulki, with FE10 Ranulf , FE10 Janaff, and FE10 Mordecai all coming up behind those two. FE10 did a great job of balancing Laguz and making some very fierce units. I’ve even taken Volug and Ulki to endgame before. All Ulki, Ranulf, or Janaff need to be incredible is to be Bexp-pumped up to level 30 and fed a Satori sign. They all become insanely powerful and need virtually no investment after that. Just feed them some of the copious Olivi Grass available and watch them tear s**t apart. The reason I’m merely mentioning Ranulf rather than considering him for best is because he suffers from the Cater Laguz meter which makes him eat Olivi Grass more frequently (and he does require a notably larger amount of Bexp to hit level 30 than Janaff or Ulki do). Janaff and Ulki would also be about equal were it not for Ulki having the much superior Vigilance to Janaff’s Insight (they’re both better Adept users than any Beorc unit you have in the Greil Mercenaries, by the way, with their amazing Mastery Skill activation rates and higher speed stats transformed). Mordecai gets mentioned for being an absolutely amazing, underappreciated tank. To give you an idea of how good a tank he is, Mordecai starts with 32 Defense transformed at his base level; Gatrie doesn’t hit 32 Defense until he reaches third tier.

So between comparing Ulki and Volug, Ulki requires virtually no effort and can just have what resources he needs casually dumped into him to become a destructive force that doubles every enemy and has at least a 36% chance of activating Tear for each hit (Adept for even greater destruction optional) and has flying utility and a very solid affinity to support others with. Meanwhile, Volug is one of the Dawn Brigade’s three amazing Earth affinity units who can attain pseudo-invincibility through a support and if used as regularly as any other unit should have an S rank in Strike by Part 3 which makes him continue to be a force to be a reliable offensive force. They’re both fantastic, but I guess Volug is more valuable to the Dawn Brigade than Ulki is to the Greil Mercenaries (Ulki’s easier to take to Endgame, but neither are essential to the simplicity that is FE10’s Endgame anyway, so that doesn’t seem to matter very much).

Worst: Easily Lyre. No offense to speak of and a Cat Laguz meter make her start in a really big ditch she’ll be futilely clawing for a very long time to get out of.
