Entry level machines are built to a price point so precision fits and run out are at the bottom of the priorities list. As precision goes up so does the price. More expensive materials are needed and much there is much, much more labor involved in their design and manufacturing.
KF 20 Technical specifications
KF 16 L Vario Technical specifications
Using your dimensions from your original post as an example look at the table travels given for both machines. The travel shows the maximum amount of movement for the table end to end. The KF 20 table moves a total of 235mm (in the X-axis) which means you cannot traverse the full length of a 350mm long part. It can be done in multiple setups by working on half of the length, then removing the part from the table and shifting it to the side to finish the other half.
The KF 16 on the other hand would be able to reach both ends of the 350mm long part without having to move the part on the table. For a vise I would suggest you go with 100mm jaws. I think this would be a good size that would serve you well on both machines. I would be somewhat partial to the PS 100 myself. If you were working on small model sized parts a 50 or 75mm vice would be OK, but for general shop use I would want something larger.
