PlugOnce vs Android File Transfer vs OpenMTP
All three apps can take part in an MTP transfer. They differ in the device and workflow they focus on. If you use a Nintendo Switch with DBI, that workflow is the useful point of comparison.
Short answer
For general access to an MTP device, a regular file client may be enough. PlugOnce is built for one workflow: Nintendo Switch running DBI on a Mac.
PlugOnce vs Android File Transfer
People try Android File Transfer to browse Switch files through DBI. It may be enough for a one-off copy, but one M2 MacBook Air owner reported an intermittent connection. PlugOnce shows Switch storage and manages a DBI package queue. One report does not describe every AFT installation.

OpenMTP serves Android and other MTP devices; its author lists split panes, drag-and-drop, and files over 4 GB. It is the more general choice if you also use an Android phone. PlugOnce focuses on Switch with DBI, a package queue, and the result of sending packages.
OpenMTP features in its READMEWhat PlugOnce adds for DBI
- Shows available Switch storage and free space before a transfer.
- Queues packages and shows the progress and result of sending them to DBI.
- Moves files between Mac and Switch and helps back up saves available in DBI.
- Keeps failed operations in history so you can retry them.

OpenMTP capabilities come from its author's documentation. Complaints are individual user reports; they do not prove that any tool fails for everyone.
