I like both, definitely.
To me they are the same--just because Lyra was designed from scratch doesn't necessarily make her a different character (Silver's name defaults to Heart and Soul in the remakes, are they different? And I'd say Sabrina's redesign is even more drastic than Kris/Lyra's).
I really love Lyra's adorable outfit (especially that hat--I want it!!), and Kris's more tough, simple design is super cool, too! They're both great.
