A suggestion on how you could approach it: try to make a table with 2-3 columns for the solutions you and I are comparing. And add a row for each aspect or characteristic you want to compare them with respect to; for example, usability, ease of implementation, room for error, you name it. In each cell, put either + or - if a solution is clearly managing that aspect well or badly, or a detailed comment. Try to express all of the things you're feeling and that are coming to your mind. My comments are written with a table like that in mind, they easily translate to one. Once you have made your table and established that we disagree on what some cell should contain or what rows/columns should be present, feel free to get back to have an actual discussion.
