aside from the handle shape, does the actual bottom of the vitaquick and vitavit look identical?   i'm looking to get a vitavit premium 10.6qt   and also a vitaquick / vitavit comfort Pressure Skillet (only) 4.2qt which is the bottom only. i'd like to use it with the vitavit premium lid.   comparing vitavit premium vs vitqauick/vitavit comfort, obviously the handles are different: https://www.fissler.com/us/products/product-detail/vitavit-premium-pressure-skill
