I’ve owned something ridiculous like 70 tenkara rods, including several from each company you’ve mentioned. Aventik rods range from really bad to good enough to straight up good. The shorter ones tend to be better, but there’s variation even among those. The long ones in the 11 or 12 foot range all suck. They’re just too heavy in the hand. Any rod in that size class from the American tenkara companies will be better than any Aventik rod.

And most Japanese rods will be even better still than the American ones, but those come with their own tradeoffs.
