If it's for a low tech non co2 planted tank, I'll go for a HOB as it free up more space internally and looks nicer, as well as easier for maintenance. But if its for one with co2 injection, internal filter may be the better choice among the 2 as HOB may cause lost of co2 due to more surface aggitation created.
