Recommended UV sterilizer for 70 Gallon

[Gobrian44]

What UV sterilizer would you recommend for a 70 gallon tank. I have a small one now but i think its time to up grade its not the right size for the tank. What is the best longest lasting brand u guys would recommend? i have a AC110, FX5 and Xp3.

THANKS!
