Very recently Dario Gil, the head of IBM’s research lab in Yorktown Heights New York said "Imagine you had 100 perfect qubits. You would need to devote every atom of planet Earth to store bits to describe that state of that quantum computer. By the time you had 280 perfect qubits, you would need every atom in the universe to store all the zeros and ones." If your Qubits aren't perfect then you're going to need quantum error correction which will use up a lot of your Qubits, so a few pretty good Qubits is better than a lot of crappy ones. Gil has developed a new way to measure the power of a Quantum Computer he calls "quantum volume" which takes in account both the number of Qubits and their quality. That's what's so exciting about Microsoft's attempt to make a Topological Quantum Computer, if they're successful their Qubits will be of extremely high quality requiring little error correction.
