Welcome dreemesicl! You may want to check the Vegetables & Fruit forum, which has several discussion threads specific to tomatoes.
This one is a bit lengthy, I can't slog through that many responses myself, but has valuable information on heirloom varieties.
The thread "Welcome to the Heirloom Tomato thread!" in
Vegetables and Fruit forum
This one is more manageable (so far) and focuses on hybrids:
The thread "Hybrid tomato reports" in
Vegetables and Fruit forum
You can also search for 'tomato' within that forum which will bring up other threads.
I have found that tomatoes can be persnickety for me and have kept records of which specific varieties I have tried each year, noting how well (or not) they produced and how the taste was. Over the years I have been able to single out varieties that thrive in my particular micro-climate. Good luck and have fun.
