I prefer NACO.
For me, Jepp and NACO are just as easy to read. I think it's whatever you get use to
No countless hours of updating with NACO
NACO updates their charts more often (56 days) Jepp will go over a year and let lots of changes go by (see paragraph below)
NACO uses thicker, more durable paper
NACO has an experation date on their charts
And best of all, they are a lot less money
Here in SoCal, Jepp only updates the enroute / area charts about once a year. You have to reference the chart NOTAMS to see if there has been any changes. Jepp charges more money and yet they let changes go by without revising the charts. I almost busted a check ride because I couldn't find a published intersection that was given in my clearance. It was on the NACO chart, but not on the Jepp chart. I guess the proper proceedure is to reference the chart notams and then pencil in the changes.
