The U.S. Federal government has set minimum standards of
germination for vegetable seeds, see https://www.law.cornell.edu/cfr/text/7/201.31.
While all companies selling seeds must meet these minimums, some seed companies
have much higher germination rates. For example, the Federal minimum for
carrots is 55%. But companies might claim higher rates if they’ve done accurate
testing.

Open pollinated means if you plant it, grow it and save seed from it, you will get the same genetic characteristics as the parent plant in future generations. Heirloom seeds are open-pollinated because the integrity of the seed is passed down through generations.

Hybrid or F1 seeds are intentionally crossed between two
varieties of the same species. The resulting cross results in a unique variety with
unique characteristics. With this, if you plant a hybrid, grow a hybrid, save
its seeds and plant them you will NOT get the same plant as the parent. It will
revert to one or another of the original varieties that made up the crossed
hybrid.
Some F1 seeds may mature faster and flower earlier, making
the plant more suitable for shorter growing seasons. There might be higher
yields from certain F1 seeds that will result in larger crops from smaller
acreage. One of the most important accomplishments of hybridization is disease
resistance.
Plants grown from F1 hybrid seeds tend to grow stronger and
have greater survival rates than their homozygous relatives. These plants need
fewer pesticides and other chemical treatments to survive and that’s good for
the environment.
F1 seeds are often more expensive because they cost more to
produce. All that hand pollination doesn’t come cheap, nor does the laboratory
testing these plants undergo. F1 seeds can’t be harvested by the thrifty
gardener for use the following year.
So are more expensive seeds better than the cheap ones? I'd say not necessarily and it will depend on how particular you are about certain varieties, how many seeds you need, and how much helpful information you want.
