Ships & Modules

So it seems that most difficult (should be rewarding) exploraton content is tied to o.o/wh roams.
Stuff in o.o inew pretty straightforward, and can be done in mere t1 frig (at lesser efficensy).
Stuff in wh is more challenging, and I'm looking for advice.
What ship t3/stratois is better at running WH sites and some random wh struglers for extended periods of time?
Tengu? Lot'o'mids and agility are pretty sweet, but missels ammo chew up alot of cargo, also is it able to tank/ninja do deep-wh sites?
Legion? Supertank, lazors - all you need for extended roam. But... Will it be enogth?
Prot? Long point... Sweet
Loki? Don't know.. May be covert+drone sub?
Stratois... Weak tank.., but you can loose em more freely)

So which is better for the task?
