Well, let me toss in the explosives:
Alaska??? What are you going to do? Big loads, small loads? Big water? Rocky beaches?
I flew a light 150 cub for work with Aqua 1800s, and at the same time had my personal 180 cub on Edo 2000s. Empty, the Aqua floats on the 150 would take off right with the 180 cub, (800' or less), and flew pretty fast. Toss in 100. pounds, and it took a couple hundred more feet, put in 200 pounds and it took double; my 180 cub took about 200 more feet for 200 lbs was all. The Aquas could step turn a slalom like you can not imagine, and had flat tops.
My Edo's, (I have had two cubs on them, and a 180) perform well, are tough, easy to repair, and can be fitted with hatches, but they are narrow doors.
Whip runs a bit deeper V hull, making them slightly better for rough water, but needs more room to get out. Good hatch access, flat tops. A down side is that the ones I have been around have had thin skins, and guys had issues with getting punctures on rocky beaches. Also, at one time Whip used sealant in the assembly process, which made pulling them apart a smelly chore.
Aerocetts... Again, a bit deeper V than EDOs, and a tad heavier than other options. Jumbo hatches. They do not like sharp objects rubbing, as it quickly damages the gelcoat and glass- but it does not take long in a dry spot to repair!! Also, they don't leak from the bottom- you can sleep at night not worrying about popped rivets sinking your plane.
My plan, had I continued flying the Fish and Game contract was to upgrade to the Aerocetts for the lack of corrosion, confidence in they staying dry, and the good performance. Also, they can take rough water better with the V than the EDOs, and I was working lots of ocean swells and rough water.
My second choice would be Edo 2000s for their performance and ease to repair, and parts are everywhere!! They come out of the water quick!
Third would be Whips, as they are the least quick off the water, and seem to have fragile skins.
Last would be the little Aquas, because I am a big guy and am flying loaded lots of the time.
If I were only working swamps and small lakes where only takeoff distance was my concern, I would be hard pressed not to go back to EDOs
