Frankly, you can't compare our nice innocent-looking Jumping spiders, with one of these brown, soft, long-legged Wolf spiders.
The two groups have almost nothing in common, besides the fact they're spiders.
As I said, Jumping spiders have a very complex neural system (a true brain, rather than a decentralized cord of paired neural ganglions, like what you would find amongst insects). This allows quick, sophisticated movements, a wide array of behaviors, almost emotion-like and often very comical. No other spiders can emulate this, because most of them are hopelessly stupid, even for invertebrates.

Salticidae are very odd creatures. They are funny to observe because of these quick reflexes, and also because they are very curious. Usually, they won't flee away from your fingers, they will try to understand what this is. Thus, they are sometimes considered as being inquisitive creatures. And again, they can stare at you, focus their vision directly towards your face: they have an excellent stereoscopic eyesight (better than many mammals), and a very large part of their brain is dedicated for image processing only. A wolf spider would be able only to notice movements... and not details, shapes, colours with a very high resolution, just like our jumping spiders would. They belong to completely different families!
When a jumping spider is staring at you, it is really looking at you: direct eye to eye contact.
Many jumping spider species are the masters of mimicry. Here, we have one which is shaped like an ant. Even its forelegs move like antennas!

And here are some extracts of their surprisingly elaborate courting ceremonies:

They are exactly like birds, somehow. The male tries to seduce his loving one thanks to his bright colours, and many other visual and audio signals.
