Airspy R2 vs professional scanners?

I've been using a RTL-SDR for a while now and I love it, but since there's no filter in my dongle, a lot of interference disturbs the signals - both from my USB and my antenna.

I've a SIRIO 68-78MHz dipole outside, so I should get good signals. Should I buy the Airspy R2 with SpyVerter R2 or a "real" scanner like Ericsson C602, C62 etc? How can I make my reception better and remove the interference?

Hope I explained it well, radon-n
