Which datatype is ideal for large amount of text?
LONGTEXT can store the maximum characters among all four, up to 4,294,967,295 characters i,e 4,294,967,295 bytes or 4GB. This is more than enough storage for any long-form text strings. For example, a book that MEDIUMTEXT can’t hold can be stored using LONGTEXT. LONGTEXT takes 4-Bytes overhead.

About varchar(MAX)
If your data is longer than 8000 characters varchar(MAX) is what you need. You can store up to 2GB size of data this way. In varchar(MAX) fields if your data size is shorter than 8000 characters your data is stored in row automatically (therefore the data execution is faster).
What is the largest VARCHAR in SQL Server?
2 GB
varchar [ ( n | max ) ]
Variable-size string data. Use n to define the string size in bytes and can be a value from 1 through 8,000, or use max to indicate a column constraint size up to a maximum storage of 2^31-1 bytes (2 GB).
