What is the 'best' method of installing NextCloud

I can see I have two options available to install NextCloud on my Rock64 board.

1). Install Armbian and then at the terminal run $ - curl -sSL https://raw.githubusercontent.com/nextcloud/nextcloudpi/master/install.sh | bash

2).Use the NextCloud Pi Image - available here

Which is the preferred method out of the two listed above, that most people use?

What is the difference between installing with these two methods?
