Only if u need crown in anterior it matters , zirconia give more color match , because itz made in layers so all the light reflection and refraction are good therfore gives natural color , also strength is good. Other ceramics  are also good but zirconia translucent is best . But i suggest a normal ceramic crown will be sufficient if itz posterior tooth .

Better get yr work done from MDS Prosthodontist and secondly...metal ceramic capping ... also having good strength if made from good lab...and its pocket friendly as well ..Dr Guptas Dental and  Braces Clinic Delhi

Hi Zirconia crowns are the best compared to ceramics .It's completely metal free and gum friendly. Compare to ceramics the strength is higher . Esthetically its suites good .Always opt for zirconia but it's little expensive .
