I fly in them all -- nearly every possible combination of avionics you would ever see in light piston airplanes. And I see applicants all levels of the spectrum with regards to electronic tools (i.e. iPad with ForeFlight) all the way down to paper.
I'm a big fan of technology in light airplanes. GPS, big glass panel displays, and AOA indicators are wonderful advancements. But I have to say, looking at the entire cross-section of my private pilot applicants, a data point stands out. In general, those who demonstrated the best grasp of fundamentals learned in airplanes with minimal equipment; used paper sectional charts (or static, non-ownship "electronic charts") when learning pilotage; and produced a hand-written nav log for their cross-country flight assignment.
My flight instructor hat has been back in use lately as I've been teaching my 16 year-old daughter how to fly. For what it's worth, the above is representative of how I'm training her.
A common comment I hear is that it might be best for the modern student pilot to learn with the "tech of the day." Perhaps so. But I think it's easy enough to learn how to fly behind a glass panel, use GPS, etc. at any point in the training arc. It's much harder to re-learn the fundamentals when there were too many crutches allowed during training.
Just my opinion based on my experience. With the right instruction a good outcome is likely regardless of the type of equipment used.
