I have the Cylinder Stove Hunter model. I always have the air intake opened at least a little bit, so the lack of a gasket to seal the door isn't really a factor to me. If I close the intake completely it slows the stove right down to the point I have to open them back up to let it breathe a little. It does a great job.
Have heard nothing but good things about the 4 Dogs as well - just don't have the personal experience to compare both side by side.
I don't think you would be disappointed with either of those choices.
