mini-dental implants v. traditional implants for molars?

I am a healthy 43 year old male about to get a implant in the upper no. 3 molar. The area has been looked at and the 2 surgeons believe there is enough bone for a mini implant or a traditional implant. I am not sure which to choose. I am getting conflicting stories about which is better and which will last longer for getting a molar implant. what are your thoughts on this?
