Best is pretty subjective. I see that most US based sellers sell a regulated bulb. That may have better longevity as the current is controlled at the fixture. As long as the components of the regulation circuit are durable and there is no RF interference, that could be considered a better lamp. I chose to use the Asian unregulated panels in warm white. The cost is significantly lower and I've had good durability. I figured that < $2.00 a bulb gives me some leeway if they prove to be less than adequate.
Best is NOT subject in real world comparisons where members here have tried bulbs based on advertised specs and "sales pitches" only to find out that they are too dim or don't work. The "RF interference" is a moot point because 99% of people here are not looking at that. Just reply with what you have personal, first hand, experience with.
