Which has better disease resistance?

Big Beef, on paper, with documented resistance to the wilts, nematodes, and tobacco mosaic virus. Better Boy covers the core VFN trio. Both are far more resistant than a typical heirloom.

Both are heavy producers of large beefsteak fruit on tall indeterminate vines. In most home gardens the yields are comparable; site, watering, and support matter more than the choice between them.

Can I save seed from either?

No. Both are F1 hybrids, so saved seed will not grow true to the parent. Buy fresh seed or plants each year.

Compare

Big Beef vs Better Boy

These are the two classic red hybrid beefsteaks, the dependable workhorses found on every garden-center rack. Both give heavy yields of large, meaty, classic-flavored slicers on tall vines with strong disease resistance. The differences are small but real: Big Beef is the slightly faster, AAS-winning one with broader documented resistance; Better Boy is the older, hugely popular VFN standard.

Disease resistance

Big Beef carries broad resistance including Verticillium, Fusarium races 1 and 2, nematodes, and tobacco mosaic virus, part of why it won the 1994 All-America Selections award.

Better Boy carries the classic VFN package: Verticillium wilt, Fusarium wilt, and nematodes. Both are well-armored compared to most heirlooms.

Yield, size, and timing

Both are heavy-yielding indeterminates with large fruit, roughly 8 to 16 oz. Big Beef ripens a touch earlier at about 73 days; Better Boy at about 75. Differences this small often vanish in the noise of a given season and garden.

Which to grow

Pick Big Beef for the slightly broader resistance and the AAS pedigree, or Better Boy for the long-proven track record and wide availability. Both need sturdy staking or caging for their tall vines, both are F1 hybrids so seed will not save true, and both reward steady watering to keep the big fruit from cracking.
