I do think everyone here is making the point that store-bought tomatoes are inferior to canned ones. Home-grown vegetables picked and consumed at the peak of ripeness will always be better than store-bought and artificially ripened, and the likelihood of them being better than canned/frozen is pretty high.
The original top level poster did just say 'from scratch' but I will grant that if 'store bought' is what people are discussing (as the comment I responded to was, I missed the word) that I do agree. That's mainly due to the tomatoes not being bred for flavour or picked long before ripening or stored long term as far as I know, though.
