Hi!

It depends on what you want to achieve. MNE doesn't support variable-length epochs, and events don't have a duration, so if you want to use the event structure (a NumPy array) you can only use onsets. However, MNE also supports annotations, which consist of onsets, durations, and descriptions. Annotations can be variable-length, but not many functions accept annotations for further processing so far, so you might need to convert your annotations to (fixed-length) events at some point. Maybe this description could be helpful as well: https://martinos.org/mne/stable/auto_tutorials/intro/plot_object_annotations.html
