well JL Hudson's politics I think are a bit unusual (there is a little rant on the website about something I can't recall what oh yah maybe it was no credit cards or something like that) but the seeds are "mainstream" and are great and they have been very reliable.
The Plant World folks are actual plant explorers and breeders, a while ago they had a thing where you could send a bit of money to help sponsor a trip, and they would then send a selection of seeds for you to try and report on how they did! They sell Nicotiana 'Tinkerbell' their own variety which I absolutely love.
