Intervals can do some really nice things 4 sure and im either a believer in those or sustained low to moderate intensity. Swimming is crazy exercise.. i was blown away when i looked at how many calories are burnt scuba diving.. probably even more for top side swimming. Both are way more than jogging if i remember.
I love healthy exercises like swimming and tennis and will be doing both a bunch this summer.
