Probably my favorite. I'm a sucker for free shipping and free seed samples, they've got a great review section with photos and their catalogue is just eye candy for browsing. However, some people have disavowed them due to their inviting Cliven Bundy to speak back in 2019.
Good germination, and has options for disease-resistant varieties, but on the expensive side if you're not buying in bulk, and the shipping is pricy too.
I like to support local growers to me, they say their seeds are better adapted to the climate here, but I haven't seen a significant difference in my plants. Sometimes cheaper per seed than other places, but they could use better filtering options on their site.
Have varieties I've not seen on the other three, including many dwarf and micro types (just bought a few to try out growing indoors over the winter), but man what awful photos! I'll admit I'm shallow, but consistent, well-lit, high resolution photos of tomatoes are much more appealing.
