If you choose to jack it up versus using ramps, MAKE SURE to use jack stands. Do not rely on the jack alone when you are working under the car. Every year you read about someone who gets crushed or loses body parts when the car falls on them. Years ago I was working on a car just using the jack since I was not going to be underneath. I went to loosen a stubborn bolt and sure enough the jack slipped. No damage done to self or car but had I been underneath it would have been another story. I ALWAYS use jack stands since then. Even on ramps, wheel chocks are also a good idea.
