lxp vs sqlite for structured, but fast database-like format?

[DiamondToaster]

So, what I'm attempting to do is implementing Factions through MCServer API. I would like some kind of structured data type, but also need it to be relatively fast. What this database will hold is:

Faction Object:
-Name:
--"TestFaction"
-Players:
--"TestPlayer"
--"OtherPlayer"
-ClaimedChunks:
--"5, 16"
--"5, 17"
-Power
--"7"

Something like that. It would need to hold hundreds of these faction "objects". I would very much appreciate the input of more experienced plugin developers, as I'm not very familiar with the lxp and SQLite classes.
