i have both the Herakles and the Arctic tanks. Both great tanks, can handle high wattage (the Arctic goes up to 100 where as the Herakles goes up to 80, though I usually keep both in the 50-70 range). Both perform very well and quite comparable.

I personally lean slightly towards the Arctic just because I don't really like how the heat fins and airflow holes are set up on the Herakles and it kinda makes it hard to clean. But that's just a minor gripe, and you can't go wrong with either.
