A good variety for outdoors is ferline, it is one of those where you take off the side shoots all the way up. Stop the top ie nip the top so that you only have 4 trusses and be sure to keep it staked, ie put a cane in when you plant it.
My best ones were ferline, home sown in february and I have now taken all the green tomatoes off to ripen indoors, have enjoyed many red ones. My worst ones were losetto, bought plants that came from dt brown in mid june, ridiculous. Lots of tiny green tomatoes, was not worth the cost and they are all indoors now on their sprays and plants are chopped for compost
