I have a Spektrum DX3r and my son has my old DX2.0. I have had good luck with DX2.0 over the years with not glitching and good range, same now with the DX3r. Also it's nice not having to change crystals. Personal preference though i really like the way the DX3r feels in my hand.
I have a JR xr3 FM ! had it for 9 years, I can buy rx's for it for about $25 in discontinued bins at run down LHS's, has all the epas, 3 channels and a 4 model memory baby! and you all run synthesized channel spread spectrum processing or the like now, so I can use my crystals and you bail off my channel lol.. We will see how it works with the MMM and 6s, may have to join the new century
