Since I see a lot about second generation peppers not being as good as first, does that go for tomatoes too? There are those really tasty grocery store cherry tomatoes that come in different varieties in one box. They cost like 4x the others but I get them when they're discounted before they throw them away. Can I save the seeds and grow them in my containers?

We grew some cherries in containers this year before they got invaded by stinkbugs. But those that survived were the tastiest tomatoes I've had in my life.
