This is an often asked question. Almost all morphs change as they age. Better is in the eye of the beholder. For example... most animals tend to darken as the get older. This works for some from my point of view. Purple passions darken as the get older. Looks better to me, better contrast. Pastels darken, looks like crap. I have one pastel that has darkened to the point she looks greyscale. I think she is cool looking. Everyone else says she is butt ugly. Highways lighten, doesn't look bad but i wished they stayed darker.
