Shower heads, water pressure and usage Question

Folks,

I live in a 7 story condo building and have my own 40 or 50 gal hot water heater in the unit. I currently have a traditional showerhead (plumber supplied a few years ago) that supplies adequate water pressure. I am planning on remodeling my bathroom and have seen these newer, wider showerheads. Should I be concerned about maintaining the water pressure using one of these bigger heads?? Do these larger heads use more water? Logic says that a bigger head reduces pressure and uses more water... True or False?

Thanks in advance.
