Annie makes a lot of good points.
You seemed to be interested in the wolf specifically so here is a bit more info.
Wolf is basically DPS focused, Jaguar more tackle and survivability.
Wolf's excel at pack hunting.
it may seem counter intuative, but you are better off with a wolf fit with 150's rather than 200's. more EHP, more DPS can be squeezed on, if you are going to be able to break something then you will do it before you need reps so no need for a repper.

Gang variant is a remote rep chain after battle for out of station repairs, you lose 10DPS but can roam more.

Jaguar is traditionally shield tanked, much faster more like an interceptor than a DPS boat. As you say depends on play style and if you prefer shield or armour tanking... Personally I have both dependant on my feeling and role within the fleet.
Pure solo, I would likely take the Jaguar out unless I was feeling particularly confident/care free. Don't know why the jag seems to survive more, just experience... common sense would say you should get more survivability from the Wolf as it has more EHP and smaller sig but hey. Jag usually comes home, where wolf usually kills and dies more.
