I'd say the upgrade is worth it, especially since you're going from the original 3DS.
I haven't been able to use it myself, but the 3D screen apparently works extremely well, and the second stick is really useful for games like Majora's Mask 3D.
I also highly recommend Xenoblade if you're gonna pick up the N3DS, and you don't own it on Wii.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
