Dear Sir, please, answer

I made design for out voltage 5 V. 

WEBENCH propose LM2596-ADJ. Why? There is  LM2596-5.0.  Maybe I do not understand something? Please see attach

    Hi Vladimir,

    I think one possible reason for the webench to give an Adjustable option is because with this you can add feed forward capacitor in parallel with your top feedback resistor such that you have a good phase margin on your design. Therefore it offers flexibility with compensation and your output capacitor ESR.

    Thanks
