merge into pattern

So I've read about patterns a bit

I have :

                if (!(i is >= 5 and <= 7))
                {
                    inputData2[0].XB1[i] = 1.0f;
                }

                if (!(i is >= 5 and <= 7))
                {
                    inputData2[0].XB1[i] = 1.0f;
                }

Should I really reformat that as
(my IDE tells me to, cf. screenshot)

                if (i is < 5 or > 7)
                {
                    inputData2[0].XB1[i] = 1.0f;
                }

                if (i is < 5 or > 7)
                {
                    inputData2[0].XB1[i] = 1.0f;
                }

why is my IDE so adament on me using them, is there really beneficial about it?
