I can't compare it to your two choices, but it probably has the same useful capacity as my dc elev8r, with slight taste disadvantage; probably more capacity than my Buddha, maybe better taste; vapbong's on another plane. From what I've seen and from my own experience, it hits with the big boys (though probably below the max capacity of the top few) and the flavor is up there as well, though again perhaps not the absolute top.
Its simplicity, price, low power consumption and flexibility with bowls/bricks, as well as useful capacity from sipping to bowl-clearing, great flavor makes it really convenient: a heavy hitter when you need it, a flavor sipper, session vape, or sticky brick heater every other day.
