Boss Katana or Positive Grid Spark?

I've been playing guitar for about a year now and I currently have the Fender Champion 20 amp, but i'm looking to upgrade my amp. I want an amp that has lots of versatility and doesn't sound muddy at all (unlike the Champion 20 does in my opinion). I've been doing some research and have settled between a Boss Katana and a Positive Grid Spark amp, but I haven't decided which model of either would be the best. However, does anybody have any advice as to which would be better for me?

P.S. I have an Ibanez Gio for a guitar if that changes anything
