Types of snus: portion, white portion and loose. Some portion snus have smaller "bags" designed for a better, or more discreet fit.
What is a shame about the site you mentioned is that their assortment is a joke. You can't find any of those brands in a physical store here in Sweden, and thus you miss out on the popular stuff (and what I can recommend).
If you can get past that, I recommend trying Göteborgs Rape White Portion, or Göteborgs Rape XR White (basically the same but has a little smaller bag and is less runny, taste also lasts longer and it's cheaper). The former is a classic taste though.
I don't like loose very much as I want a white, confident smile. It's also bothersome.
As for non-white portion (stronger and stains your teeth a little more), I recommend the classic General Portion or Ettan Portion, you can never go wrong with those!
If you have any more questions let me know :)
