Is there much difference between 1.75 and 2.15 tires?

I have a 2009 Dahon Speed TR that I took on tours, and over the past 3-4 years it's probably done 10,000-12,000 km. I still have the original Schwalbe Big Apple 20 x 2.00 tires, but the past few months I keep getting flats every 2-3 weeks, so I think it's time to get some new tires.

I'm trying to decide between 1.75 and 2.15 tires. Would there be much difference?

I am trying to decide between the:
Schwalbe Energizer Plus 20 x 1.75 640g
(which appears to have all the same specs as the Marathon, but gummier to allow more wet traction)
Big Apple Plus 20 x 2.15 730g
(which now has a puncture strip)

The original Big Apple is 495g, and my bike is already around 18kg with all the accessories attached. I also have about 30kg of gear that I carry on the bike. So, changing to the Big Apple Plus would add almost 500g while the energizer will be only a 300g addition. On the other hand narrower tires wouldn't hold up all the weight too well.

I have tried on a Marathon Supreme 20 x 1.6 and it feels a little faster, but the grip wasn't as good on gravel, although I don't know the experience was real or just psychological.

I will mostly be riding on hard surfaces, not so much gravel anymore, but the paths here are bumpy with intermittent brick roads, and and the Marathon Supreme makes it a very stiff ride.

Both the Big Apple Plus and Energizer Plus are just 12 Euro a tire, while the old Big Apple is 20 Euro. Strange.
