My rankings probably wouldn't be the same as yours. Really depends on your own likes/dislikes.
FWIW, here's how I see them:
I like SD knives and mainly carry a knife for that purpose.
So, the Tropen is at the top of the list for me because it's designed as a SD knife. It's a big knife w/a long upswept blade and polished G10 handle that are both properly shaped/designed for SD use. It also offers 5 methods of deployment (flipper, Spydie hole or wave tab w/thumb, wave tab from pocket, gravity flick and wrist flick); something that is not available in any other folder that I am aware of. You can also use the handle for blunt force strikes in the closed and open position. Like I said, it's designed as an SD knife.
On the other hand, if your needs are more conventional and:
1) you like a larger handle w/a wide leaf shaped blade that feels more substantial in your hand, the Shaman would be the choice,
2) or, you like a classic design with a longer/sleeker blade, the Advocate would be the one to pick.
3) or, you like a longer rectangular shaped blade and consider paper thin slicing ability most important, then the Amalgam would be the choice.
FWIW, IMO, the Advocate is the prettiest, most comfortable and has the best shape for general use of the 3. It's the knife I'd want to carry to make a statement but it's not just for show; it can get the job done too.
On the other hand, the Shaman is probably the most "practical"; no one (who's not a knife person) will think much of it when they see it but it will get any job done that needs doing.
And, while the Amalgram can be carried as an EDC, the length and shape of its blade could limit its usefulness. I also do not like the "feel" of the CF/G10 laminate scales when compared w/the textured Ti scales of the Advocate or the smooth G10 scales of the Shaman. So, I personally would not carry it as an EDC.
Good luck choosing/buying 1 because the hardest thing to do is to buy just 1.
