Yellow Pear Heirloom Tomato Plant

One of the plants is my garden is a yellow pear heirloom tomato plant. I have no experience with these plants, but decided to give it a shot this year. Well, I had no idea how large it would get. This plant is over 5 feet tall and about 4 feet wide (it would be wider if I didn't have it caged in). This plant is crowding out the other tomato plant and 2 of my jalapeno plants. I don't think I will plant this one again next year. We finally got some ripe tomatoes off of this plant and they are okay, but not fantastic.
