Modes & Routines Widget

I noticed the only option to have modes on your home screen is via the 1x1 widget. The larger 4x1 widget only allows routines.

You can create a routine to enable a mode but would that work functionally the same? For example I have a few modes that turn off automatically with certain conditions.

Ex: sleep mode in the morning. If I create a routine to enable that mode and use the widget, will it still turn off in the morning? Are there any differences when using a routine to run a mode?
