No, the VIC 20 was the rich man's ZX81... It preceded the Commodore 64 by about 3 years. The 64 replaced it, when it was released.
We used Commodore PETs at school, 2000 and 4000 series. The newer PETs that were launched around the time of the C64, and the Commodore 700 were lovely, much nicer than the C64, but they were too expensive for home use.

We also had PETs at college for the first year.
