You have the option to also consider full-hard, 22-gauge wire or full-hard, 24-gauge wire, which will give you even greater firmness and rigidity in the finished shape, it is just less forgiving when shaping.
Part of the answer of which wire to choose depends on what, if anything, you'll be stringing onto the wire. If you add beads to your current design, be sure to check the bead hole size chart to get an idea of what wire will best suit the beads. A thicker wire will add strength to your piece and it will decrease the possibility of it being crushed or deformed.
In reference to wire gauge sizes, the higher the number is the thinner the wire is, which is opposite of what would seem logical. Check out this handy Wire Gauge to Inches and Millimeters Conversion Chart to help convert most standard sizes in either direction.
