will powerline work as good as wifi

I am now in a large house (renting a room) and the router is in the front of the house and I am in the back. Don't know if wifi will have the range and stability so I am looking at all the alternatives from running a long cable to powerline.

looks like a powerline adapter set will cost about $50

has anyone use these or other powerline adapters?

how is powerlines speed? Are they more stable then wifi?

powerline cost is good i am just currious about the performance
