I've always had good success with them.
I'd recommend you add calcium to the soil via eggs shells etc. to hold off blossom end rot.
Make sure you use good tomato cages (strong). They're indeterminate.
"Better Boy tomatoes are indeterminate, which means they should be grown in cages or staked tepee-style. Because of their large size, 5-8 feet (1.5-2.5 m.)"
Here's an additional reference:
"Beautiful bright red, firm, 8 ounce deep globe shaped fruits are smooth and really delicious. Some claim it's better than Better Boy! You be the judge! An excellent choice for mid-early production. Vigorous plants produce heavy yields.
Indeterminate"
