I am considering veneers. I am a clincher. Is Emax or Zirconia better for me?

If you were my patient, I would recommend Zirconia.  Emax is a tiny bit more cosmetic, but not as strong as Zirconia.  I would also recommend that you get a mouth guard to be worn during the times that you clinch the most, whether at night during sleeping, or during the day during stressful times of your life.  Zirconia is very very very strong.  It is basically the same stuff that CZ's (fake diamonds) are made from.  Not as strong as a real diamond, but close enough to be a very durable tooth.   More importantly than which material is used, is the dentist that you choose to do the veneers.  Make sure the dentist has real before and after photos of his or her actual patients and make sure that you like the photos.  This will be the best indication that the dentist really knows what he or she is doing. Good luck and I hope this info helps you.

both are good , and they will last, the only problem would be to have a good diagnose of your bite, because if it isn't so, then you will brake any one you choose, remember that the way you bite, is what it broke the original teeth, so no matter which material you use, it would be exposed to the same strength.aesthetically both look the same.now in some cases, with strong bites, crowns are better than veneers

Since you are a clencher, if you want veneers, these two materials are the strongest available today and either would be a good choice. Emax is more esthetic, but not as strong.  Traditional zirconia is about 3 times as strong as emax.  Today there is a new material, zirconia anterior.  It is more translucent than traditional zirconia and will give a more esthetic result.  The strength is between emax and traditional zirconia.  I believe this might me the best material today for patients that clench their teeth.  After your veneers are completed, you should be fitted and wear a nightguard to protect them.
