Rp,
You can place a floorjack anywhere on the frame or suspension. A Hi-Lift needs places to put it and slings and such to lift. A floorjack is just flat more versatile. Harbor Freight has a couple different aluminum ones as well as Costco. I just saw the Costco one tonight. Cheaper and bigger than the Harbor Freight one I bought. About 50 lbs. You'll be happy you have a floorjack if you get stuck in the dirt or have a flat in the dirt. I've had Hi-Lifts. Slow to put into play.
