There are about forty million filter threads and every one of them is a collection of personal opinions which in the end lead to nothing.
I assume you will be going canister since it is a large and planted tank.
That means any Rena, Eheim, Fluval or Marineland product will serve you perfectly well. I guarantee you that this thread will eventually be a list of everyone's preferred brand and the truth is they are all just as good and just as bad as each other for various reasons.
My only advice is to go for two filters. It will not only be a failsafe in case one stops working, but it will also provide you with better mechanical filtration as well as easier maintenance.
In addition to that two filters allows you to do more customization of your water conditions. For instance I run one filter just for peat on my blackwater tanks.
