That's an incorrect comparison.
PS4 Pro and Xbox One X are high-end models with new price points while the New 3DS models assumed the price points of the models they replaced. New 3DS is more comparable to PS4 Slim and Xbox One S, because they all replaced models that were phased out shortly afterwards.
They are fine comparisons, Nintendo can release a more powerful model while also releasing a smaller model like those 3 did.
