I am sure they are both good quality radios. Another thing to consider is the cost of rx's. AR6110e's (6-channel JR/Spek) are around $50 and a quick search shows the 2.4 airtronic rx's to be $75 (7-channel). Also I just ordered 4 mini (JR/spek) rx's from hobby king at $8 a piece plus shipping:

I will report how well they work when I get them.
The 10 channel airtronics rx looks to be about $179 and the 8 channel JR/Spektrum rx is about $120.
