longest lasting nano paint lsealant?

CX-5, fwd auto
I have already read a lot of reviews on nano paint sealant, but unable to come to a conclusion of which one last longest with easy application. I looked at Judo juice, wolf's chemical etc but if anyone knows about detailing your advise is appreciated.
 
Sealants only last anywhere from 1 month to about a year, depending on the weather condition and driving environment. Hard to say which one is the best since it really depends on the price and preference. I currently use BF Crystal Seal, not sure how long it actually last but I only apply it every 6 months to a year on my cars but plan on getting Chemical Guys Jetseal later on...
