I have a Linux computer (Dell Chromebook 13) connected to the Microsoft Mouse 3600 Bluetooth (BLE 4?) and it was rock solid. The mouse picks up immediately whenever the computer is on. It was almost miraculous how well it works. The mouse is really quite darn responsive too. That is, I use the cutting edge Linux distribution (Ubuntu 17.10) -- it was pretty darn painful even on 17.04. I have another keyboard that is on Bluetooth 3.0 that fucking disconnects every other day. So YMMV - I think BLE mice and keyboards are much better in terms of 'just works' unless you pair them with a whole bunch of devices.
