The Lincoln has a MUCH better receiver that the 2950DX. Both have good TX audio, but I think the Lincoln has a smoother, more natural sound. That can depend heavily on what microphone you use, but when i talk on my Lincoln mobile with an Astatic 575 mic, I get lots of people that can't believe I'm not on a Kenwood/Icom/Yaesu base rig.
Some people say that Lincolns are not good AM talkers. It is true that they don't have assblaster loud AM, but if you adjust the AMC and use a good quality mic, they sound very good on AM. Absolutely beautiful, crystal clear audio. And if you really HAVE to have assblaster AM audio, there are a couple of mods to accomplish this, too.
They really are fine radios, and you can see the quality if you open one up and compare to any RCI radio.
