Difference between etherscope and linkrunner

Hi,

we now have a linkrunner(old) and a aircheck G2, and we are looking to uprade to a 10g tool.

I am unsure of the exact difference between having a linkrunner 10g and a aircheck, or having a etherscope nxg. The website doesnt really give much info, and I tried the live chat but the rep wasnt helpful, didnt seem to know.

Has anyone tried both ?

Does anyone have experience, or recommandations ?

Any hints ?
