Update: I've now watched the available episodes of Berserk of Gluttony and Ragna Crimson. Both are good fun.

Berserk of Gluttony so far has not been much more than an edgy fantasy power-fantasy. But it's executed well and has been enjoyable. I think it's a little darker than the typical power-fantasy. The bad-guys are laughably evil and I'm not sure if the plot is going anywhere interesting.

Ragna Crimson is more story focused. I supposed this show also has the makings of a power-fantasy, but it has not leaned too heavily into the wish fulfillment aspect. The characters are more interesting. The bad-guys are also laughably evil here, but in a way that's more pure (literally being monsters helps, I guess), and thus a bit more horrifying. Every reward has a price, and you often do not know what that price actually is.
