Lee,
My taste buds are still in decent condition after 55 years or so and they really cannot tell the difference between the fruit of a store bought and a plant of the same variety I raised from seed!
Honestly, if all I wanted to raise was the popular varieties of toms and peppers, it would be stupid for me to grow from seeds, unless I really wanted to waste time and money. You figure the cost of seeds, potting soil, lighting, water, containers and your work and no way can one raise three plants for $7.50 per variety. But if you want those special, best tasting toms and peppers, seeds are the only way to go.
Of course, I know you know this!!!!
Mike
