I'm like you,looking for a seedbox and I had same as your options
I don't know which one to pick
But one of my friends suggested to strongly have seedbox from seedhost.eu

I liked thier prices but there is bandwith limit, & my friend isnt complaining about it
he says their speed is high, and he has been uploading 20 torrents there for two weeks and the bandwidth of 2T consumed only 400G

with all what he said am still not sure what to pick from all of those compnies and choices

When you settel your choice about one I hope you post it here
