they are all more or less the same. just pick something that is appropriate for the size of your tank. I have had good success with the Aqueon QuietFlow filters. I have one thats been running for several years now without any problems. I like how the filter automatically starts working when you plug it in. you dont have to mess with filling it up with water first or any of that which you sometimes see on the cheaper HOB's
Alternatively, you could get an internal filter that you could hide behind plants and it would distract less from the seamless look of a rimless tank.
