I recently got a couple of the NooElec NESDR SMArt v4 dongles, and I've been quite happy with them. I also have a few no-name dongles, with one of them that has been running rtl_433 for years now to graph outdoor and basement temperature and humidity from off-the-shelf sensor units.
The NESDRs are much more accurate than the no-names and don't drift. I was flabbergasted when I plugged one in, tuned it to a nearby NOAA weather transmitter, fired up gqrx, and saw that it was spot-on without having to adjust the frequency error. Also, they have SMA connectors instead of the dodgy barrel connectors on the no-names.
