Cheri, take each wheel off the bike and feel its weight separately. Spin the wheel in your hands and see if the hub feels smooth and how long it keeps rotating. After you get your own wheels back do the same with them. That will give you a comparison feel for the wheels. BTW, your old wheels have cup and cone serviceable bearings, so if they don't rotate as well as you'd like or feel dry or gritty, they can be regreased and adjusted.
Oil is good, grease is better.
