Which ocean is saltier, warmer and cleaner...the Atlantic or the Pacific?

I am not sure if one ocean applies to all three critera.

I believe the Atlantic to be because it's colder and most bacteria feed on warmth.
Well, it's not warmer all the time, only in the summer.
The Atlantic is on the East coast the Pacific on the West.

the atlantic is definitely warmer.

I have lived in both places and The Atlantic ocean is warmer, cleaner and more salty

I thought the pacific was warmer, the atlantic colder and saltier, i might be wrong though.
