Hey guys
I was interested in starting up
WHFB army but cant decide on an army to roll with ive narrowed it down to 4 armies whose lore I dig but not being experienced with the tabletop styles of these armies I was hoping you grizzled war veterans could give me your insights

. My preferred playstyle is a small elite fighting force which moves quickly and causes havoc when they hit home, so do tell me which of these armies would best cater to that.
Warriors of chaos
High Elves (they were my first choice but ive been told that for the points there nowhere near as killy as
id like them to be and lack strength and toughness in there more elite units)
The Empire (
Id want to make my army centered around greatswords, a general on griffon and be backed with loads of free company / handgunner cannon fodder)
Vampire counts
Now I know Vampire counts completely oppose my ideal but I still find them interesting,
Id really appreciate your experiences playing / playing against the aforementioned armies and how they function so I can hopefully narrow this down ;P.
Cheers
