Hello Kansasslider
I had the same doubt too. These leaks are not a problem for the 2080. 2075/2073/2071 models have some lots with a defect in the sealing of the filter head. As far as I know who had this problem got a new filter head.
I opted for 2080 Pro 3 because of electrical efficiency. I live in Brazil, high taxes here almost everything more expensive. and that includes energy

. In my case the difference of electric consumption would make a difference in 3 years but as it is adjusted every year, I believe that in two and a half years the electric consumption already pay the price difference.
But I repeat it here in Brazil.
If energy costs was not a problem I would have chosen the FX5 at cost / benefit. However after a little over 1 year of use I say that money is not the problem Pro 3 2080 is the best choice.
If the cost of energy is not a problem for a little more money you buy two FX5 as VeipaCray said.
If the cost of energy is important and money is not an issue the 2080 is undoubtedly the best choice.
In the next filter cleaning I'll take some pictures and do a review. But I can say that with a little over 1 year of use that the 2080 is an excellent filter, I'm really pleased with his performance.
