There are a few choice for both the BC and NC28 today, they have to do with lighting.
I personally like the filtration chambers of the BC better. The NC has some interesting design choices. That said the NC has been the leader in better lighting in the hood, yet it may lead to higher heat, cept for that fancy new LED which isn't proven yet to be that bright.
They are all the same at the end of the day when you take off the light and most upgrade any AIO aquarium.
If you want just a clown with some zoas go with PC lighting, skip the anem, they are a pain in the ass in a small tank, need high lighting and your clown with host just about anything including a magfloat. Get a frogspawn if you want it to host a coral.
