Futari wa Precure: Splash☆Star

Another duo dynamic that tightens all the great aspects of its predecessor, offering memorable villains and a fascinating plotline that really works for its fifty episode runtime. A greater focus on the environment that makes for some beautiful backgrounds and battles.  

If you're looking for a y2k series with action, comedy, and cute girls being magical friends - both series have those a-plenty! Both casts are school students with slice-of-life episodes following their school lives. Both casts are highly unlikely friends with very different personalities and backgrounds. Balala, like SplashStar, is the first 'reboot' in a magical girl meta series, but you can start them without needing to see the previous versions.
