What is the best DS system, objectively?

I've seen so many posts online about the pros and cons of each console, but in my opinion, just because of the fact that I can play pretty much anything on my N3DS XL, it is and always will be the best for me overall. That being said, the DSi XL and non-XL are GREAT consoles and I really enjoy having mine for non-3DS titles. The dual IPS screens on the DSi XL look amazing and for non-3DS games look way better than playing those same games on the N3DS.
