What is the difference between VARBINARY and binary?
Even though BINARY and VARBINARY are binary byte data types, they have differences when it comes to storage. BINARY stores values in fixed lengths while VARBINARY stores in variable depending on the type of values. Values in BINARY data type are padded with 0x00 which is not the case with VARBINARY.

What is the difference between Nvarchar and Ntext?
ntext will always store its data in a separate database page, while nvarchar(max) will try to store the data within the database record itself. So nvarchar(max) is somewhat faster (if you have text that is smaller as 8 kB). I also noticed that the database size will grow slightly slower, this is also good.
Is it bad to use VARCHAR Max?
In my opinion, using VARCHAR(MAX) always instead of VARCHAR(N) is not a good practice. My reasons are: You cannot create regular index on a VARCHAR(MAX) column. So, if you want a indexed string column then you have to go for VARCHAR(N).
