I own a bunch of SDRs and even the cheapest one will beat most conventional receivers, it's a matter of wanting something to carry with me and listen to in the car, because at my apartment, the RFI is just amazingly bad. I did the car SDR+Laptop thing for a while, it worked fine, but it was pretty inconvenient to be lugging the laptop, SDR, and mag mount antenna (or the long wire one) around and putting it into the trunk every time I got out of the car. And I had to go through several USB cables to find one, and it surprisingly turned out to be a Monoprice cheapy, that didn't radiate major levels of RFI itself that affected whichever SDR I was using. I ordered a new FM trap filter as I can't find the one I've had for years. I had it a couple of days ago! That's a problem with some of those small items. It will surely show up after the new one comes. I had a box of .22LR ammo that I owed a friend in a trade. I looked for months, and finally bought another one, at more than double the price the first one was. The day after it came, the old one suddenly was found. I gave him the new one.
I don't believe any AOR radio does trunking, so that makes it semi-useless IMHO.
