Anything that is reverse flow can work well. They all basically do the same thing.
After the first few years, I would have spare uni seals on hand - they do degrade from the co2. They are not hard to get or anything, but it is better to have them than to wait a week.
I have been using CaRx for decades and the best ones use O rings inside of tight fixtures, but even these get brittle over time.
