X20 IQ will be as good as?

Dear forum members,

what do you think? Given the improvements od X20 compared to X10 will the IQ of new fuji premium point&shoot's be better than the competitors such as

Canon G1X,  G15, Oly XZ2, Panny LX7

I owned X10 and despite it "largish" sensor and 2.0-2.8 apperture I wasn't completely satisfied. I most circumstances (indoors) I had to use ISO 800 or higher and things were to grainy for my taste.

So, how would you compare the formentioned cameras?

Cheers
