What Sentinel character should I evolve to 5*?

[MetalCheese]

I just got enough evo shards to evolve a Sentinel character, and the three that I'm considering are Allied Bomber Boy, Golden Son, and Soulless Demon. Which one would be the best to evolve if the other ally I use can be Hellhound or Magus Allied Soldier, and the Eddies I can use are Samurai, Carriage Rider, or Soldier?

All three of these characters have their merits, imo, and I've brought them all up to 5*. For your team though, I'd level the Bomber Boy first... his damage output--even unsharded--is impressive. Throw some Ward Energy and Freezes on him and you're good to go.

There was a time I would have said Soulless Demon first... but he doesn't seem to hit like he used to. (Even post-de-Overwhelming, as it were). As for Golden Son... he's a great healer, but he doesn't hit very hard. If healing's what you're after though, I'd say he's the way to go.
