There are other issues as well from my experience which once again leads back to that essentially only you can determine if these radios work for your situation.
Both radios have features I like and I've also said it would be nice if they combined efforts and put all these features together into a single radio line. Of course the down side to that (not that is will ever happen) is that we'd be talking about a single vendor - never good for the consumer!
I think this is what starts a lot of the "wars" that GRE is better and the next guy says Uniden is better!
It really boils down to the fact that both do work but for some, one brand will work better than the other.
If one works great for one person, it does not mean it will work well for a guy across the state or even on the other side of the same city!
Scanning used to be horrible back in the days before triple conversion radios if you lived in an area with a lot of RF and a NOAA WX transmitter. Then GRE came along and released the triple conversion Pro-2004 for RadioShack. That alone made a huge difference in how well scanner radios worked in such areas. Those that lived in rural areas probably don't know what intermod was.
Then trunking came along. Trunking by itself did not really introduce any reception issues per se. It was digital modes that seemed to re-invent the 'my scanner is better than yours' wars!
I agree 100% that for some users, one brand will work way better than the competition and at the same time, some users will find they need a model from each manufacturer if they wish to hear it all.
It's a shame not everyone can afford to purchase one of each and then return what does not work or keep both if both work.
I gave away a lot of pre Pro-2004 models when I moved from the country to the city. Gave them to friends back in the country where the radios worked fantastic but they would not work where I moved due to the high levels of RF. I could not handle the constant intermod and co-channel interference!
And decent notch filters were unheard of back then. At least anything affordable.
I knew how to build stub filters but they were so wideband that I'd end up killing the signal I wanted. Then triple conversion scanners came out and they were like Alka-Seltzers!
Today, I have dozens of scanner radios (plus commercial radios). Many are old crystal models that still work fine thanks to affordable (and very tight) notch filters and multi-couplers etc. I'm once again able to enjoy the old radios that worked so well before I made the move back into a city chock full of RF.
Not everything works perfect so you must play with filters and antennas until you find a combination that does work but that alone is half the fun for myself.
What amazes me more than anything is that anything works at all with all the RF floating around in your typical large city! It can be a real challenge making it all work without one thing killing off something else.
I no longer give radios away, instead, I find ways to make them all work one way or the other.
The downfall is I now have more radios than I have room for!
I manage to fit them in though but I still have not overcome the problem of only having two ears.
Maybe in time, a very long time, human hearing will have evolved into a digital format. I guess if that ever happens though, we will all have been replaced by machines and robots!
