Diffuser VS. Reactor

Reactors are more efficient, due to the larger volume of water in contact with the gas. Plus a reactor is sealed and the extra gas cannot escape.
 
Reactors...but...they are only good if you use canister filters.

* Edit * Didn't look at your links. Not the type of reactor I was thinking. This one is a power head and doesn't rely on the filter like others.
 
IMO, glass diffusers best serve small tanks. I wouldn't use one on anything over 25G.
 
Reactors are always better.
Diffusers are just cheaper and not as efficent, but if you are on a budget---Diffuser.
 
if this was a poll it would be very one sided... reactor.
