software comparison (abaqus, ansys, flac, udec)

hi everyone, right now I am writing my reserach proposal and met some question really need your help. thank you in advance!

my reserach field is to study the boundary effects in a lab test on the obtained material properties, I have decided to choose abaqus as my numerical tool, but in order to explain the merits of abaqus (robust at solving complex and nonlinear boundary conditions explicitly) over the others, i need make a comparison among other popular modeling softewars, which I am not farmiliar with, i made a table, some contents are missing or questionable, could you help me firgue it out?

much appraciated if you can give me any suggestion!
