I suppose. I just think the better pots are more functional.
For example the Blichmann-
-easier to move because it is lighter weight
-flat bottom
-stepped bottom, extremely nice for MLT
-dimensioned specifically for brewers
-awesome sightglass means I can check volumes through my entire process and it is easy to clean
-a very nice thermometer (I have not had any problems with the placement, but others have)
-a great diptube system
-three piece ball valve (which contrary to my earlier belief is actually much easier to take apart and clean than a 2-piece)
-lids
-handles
-and you can be proud to own them and show them to friends
IME, keggles are very heavy and cumbersome to work with. Aluminum is a pain for cleaning, it scratches, it gets bent, it looks dull, etc.
