Bluetooth from laptop, or ANT+ with USB extension cable?

Hi.  I have the option of using either Bluetooth or ANT+ with my devices.  I’m wondering which one I should choose?  If I go with Bluetooth, my laptop will be approximately 4-5 feet away from my smart trainer.  If I go with ANT+, I can use a USB extension cable and put the sensor right next to my smart trainer.  Any suggestions?

I go with ANT+ using an USB extension cable and put the sensor right next to my smart trainer. I used to just plug the dongle strait into my laptop but with an extension cable signal is not dropped.
