I'd say either would do the trick...
I personally love the look of a planted fuge, but if your keeping everything in your sump room ,may be no point in it...
There are quite a few macros that rate in as a better nitrate sponge than cheato, but cheato undoubtely works, and is safe.
If you do a planted fuge, you can buy alot of macros that not only will reduce trates but could also be used to feed your fish when you crop them where as you will just throw out cheato...
