A baffled filter is always the best option in my opinion. I have a friend who has bettas, and I have tried to get her to put them in a filtered tank, but she doesnt have filters on their one gallon tanks... and every few months one dies and she has to replace it. The longest she has had one live now is only 7 months. Of course, when she finally decided to do a filtered aquarium (10g), I told her to put a divider in it and let her two living bettas enjoy it, but no, she opted to buy neons... killed those... bought more... killed those... now she is dealing with guppies.
Anyways, my point is, I always feel that a filter (and heater) is deserved by any fish.
The high planting is cool too, but I would add a bubbler for water movement so it doesnt go stagnant.
