Why has Josie Davis enjoyed a more successful career than Nicole Eggert post-CiC?

I mean, Josie isn't necessarily an A-list star in her own right, but she continues to book acting gigs (especially in Lifetime and Hallmark movies). And I just saw on her Twitter account that she's going to be on Stumptown on ABC.

With Nicole, it seemed like her career more or less "peaked" with Baywatch, which came after her run on Charles in Charge ended in 1990. And in recent years, Nicole has pretty much been relegated to doing a lot of reality television. And more recently, she's been in the news being the owner-operator of an ice-cream truck.

I always figured that Nicole was being set up to be the breakout star of Charles in Charge since she was the resident teen pinup/bombshell while Josie was looked at as kind of the more nerdy and plain "kid sister".
