I chose 'other' as I like to do all the choices. I have seedlings/flasks for the challenge and also as often that is the only way to obtain certain plants.
I like NFS plants as they are cheaper but you get to see the flowers within a year plus it keeps your interest up
And I like to get flowering plants and see if I can flower them again next year.
I think a selection of different plant sizes keeps the interest up as although I like seedlings I wouldn't want to buy only seedlings as I need new flowering orchids in my collection now!!!
