\(y=- x^{2} +8x-15\)
written in vertex form, we have,
\(y=-(x-4)^{2} +1\),
i.e. vertex = (4, 1) and maximum value at y = 1.
 
\(y=- x^{2} +2x-3\)
written in vertex form, we have,
\(y=-(x-1)^{2} -2\),
i.e. vertex = (1, -2) and maximum value at y = -2.

Therefore, \(y=- x^{2} +8x-15\) has the larger maximum.
