What do you use to manage files between Android and macOS?

I've never been completely happy with the available options for transferring files between Android and Mac. Some have reliability issues, others don't really feel native on macOS.

I'm curious what everyone here is using today and what frustrates you the most.

Over the past year I've been building a native macOS file manager for Android, mainly because I wanted something that felt more like Finder than a basic transfer utility.

I'm trying to prioritize the right features before releasing it.

Which features would be most important to you?

So far I've focused on:

Quick Look previews with the Space bar
Multiple Android device support
Folder size calculation
Finder-style navigation and keyboard shortcuts

What would make you switch from your current solution?
