Pad friction material is made up of a cocktail of ingredients. Different compounds have more concentrated amounts of the particular materials stated in the description to give varying wear rates, bite/feel performance as described on the link you provided.
As you already know resin is softer with good initial bite, supposedly 'quieter' but the downside is faster wear (especially in wet conditions).
As you know metallic/sintered are harder, wear less quickly and are less effected by wet conditions.
Semi metallic is somewhere inbetween.
Never heard of multi metallic but the description says 'ceramic' which I'm currently running on my front brake. I don't notice any difference at all with the ceramic compared to the usual sintered pads I normally use in mostly wet, muddy conditions.
If you're happy with how long your resin pads last and their performance for the conditions you ride in then choose those again.
Alternatively it sometimes comes down to personal preference so maybe try out the others to gain slightly more of the stated benefits each compound has to offer.
