Which one is better: aetna vital savings/GE wellness plan? - ge dental and vision

I need a root canal on my molar and the need for a dental plan as soon as possible. Who has more of a discount, saving vital Aetna / GE Wellness Plan? Both said they give you about 10-30% reduction, but how he should know before you go for them?
