I am TOTALLY confused as to whether I should go with LAVA Plus or E-MAX veneers? Please opinions! (photos)

This one is easy.  EMAX!!!!  I have placed thousands of these restorations and can tell you that there is not another material that has a combination of the strength and aesthetics that Emax provides.  LAVA is a fine material and very strong, but does not compare in aesthetics to Emax.  You should have a stunning result. Good luck.  

Replacing composite bonding with veneers is an excellent decision. I have placed thousands of restorations and can tell you that I use Empress and Emax for my patients. Lava Plus, a translucent zirconia, is being recommend by the lab due to its strength, but Emax is very strong as well and provides the best esthetic results. I hope this helps.  Follow me on RealSelf for more answers.

Congratulations
on a wonderful decision to replace your resin bonding with veneers. The lab
suggests Lava Plus because of the strength of the material, however for a
combination of strength and beauty, E-max is hard to beat. Lava Plus is a translucent
Zirconia and would be my choice if strength was a prime consideration, but from
what I see in the photos, E-Max would be my my material of choice! It is very translucent and strong as well!
