Which is the most significant (important) console in history?

If there was no NES. There would be no market for PlayStation to enter in the first place.
The PS1 was above and beyond the best selling system of all-time at that point, but it didn't save the market from anything.
The numbers you provided just proves my point that the market was already as big and as popular as it had been at that point, and still growing when Sony decided to throw their hat in the ring.
