Having spent 20 + years with Jepp/Aerad, I have to disagree with the dislike of Navtech.
The newer version that I have used these last 2 years is for me superior in every way to Jepp.
I even know where to find the chart I want, as it appears (to me) they are sequenced logically.
Now using the electronic version, and still a confirmed fan.
Perhaps the problem, is that the EFB is Navtech, but, in many aircraft, the info on FMC is Jeppy derived.
It always struck me as a little strange that this "discrepancy" is accepted by EASA.
