Teddahlia , I have found the same conclusions with growing tomatoes. The heirlooms can't thrive in my cooler summers, and Big Beef is the winner, replacing Early Girl, for me. To tame the 6'+ cherry tomatoes and a variety called Golden Rave that grows to 7' tall and produces a record breaking amount of produce....a few years ago I convinced my husband to help me build(I supervised😉) unorthodox tomato cages, that can hold the most vigorous growing tomatoes. Not the prettiest, but they hold up to strong autumn winds and 6'+ tall plants. 
I forgot to say, if you're selling the cherry tomato seeds (or cuttings), I'll buy some!
