This is no longer the case unless you are using and non standard boot pool. ZFSBootPartition is still usable but really a legacy method, as you will be limited on a 2TB partition for your pool vdevs GPTzfsroot is the way to go these days as it will work with large drives (2TB+). One thing to note about that guide is that it does not specifically align the partitions to 4k, which should always be done for all drives, advanced format or not. There is also the ashift=12 question as well. As a general rule of thumb, you should opt for ashift=12, but I have been lead to believe there are some work loads that work better on ashift=9 even on advanced format drives, therefore its probably worth doing some testing to make sure you make the correct choice for your senario.
