For those of you that have spent a decent amount of time playing on both handhelds, which do you prefer and why? As for me, I've decided that i'm going back to my regular Aqua blue 3DS and just using my XL for VC GameBoy games in 1:1 Mode due to the larger screen size. 
The XL KIND of dissapoints in terms of brightness, along with it's 'warm' color temperature, slightly darker colors(some people are saying they're richer?Really?) and the obvious less crisp, more jaggedy & stretched picture quality of the larger screens. Games still look great, and the 3D although not quite as intense is just...well...BIGGER.
Which is great obviously. It actually seems a bit more natural, but the jaggedy less crisp graphics on the larger screen can make it seem not as pronounced or sharp at times. But after testing out titles side by side on both consoles the difference in terms of Brightness and PQ is quite noticable, especially with Resident Evil: Revelations.
Plus, when you plug in the charger/adapter into the regular 3ds it gets a fantastic boost in brightness, the whites get brighter, the colors become more vibrant and really pop. This isn't the case on the XL. if the warm temperature was bad enough, the Charger/adapter cable doesn't even increase the brightness whatsoever...I tried to get used to it, but whenever i'd flick on the regular 3DS + the charger cable I'd instantly be wowed by Brightness combined with the neutral color temp. The larger screens of the XL may make the experience more engrossing and grand, but the fact there's a few sacrifices along the way have thrown me off. The regular 3DS comes in either neutral or warm color temps, it's basically just a BIG panel lottery. I happen to own 2 aqua blue 3DS's, one that's neutral and the other being warm, and neutral I'd say looks a lot nicer since you get 'white' whites instead of yellowy' whites for ex, ect ect.
Plus the XL is looking a little cheap I'd say...Doesn't scream NextGen like the more sleaker, glossy, sparkly, multicake layered, detailed and brilliant desgin of the original which clearly had a lot more thought put into it. The XL looks like it belongs in the DSi family. It's more functional, clean and to the point, but it's very uninspired and bland imo. Looks great(blue at least) on the outside, but once you open it up it's just blah. Some prefer it, but it's design change i'm guessing saved Nintendo a few bucks. And heyyy, no finger prints for those that i care. I don't. lol
At least it's more comfortable than the regular 3ds due to the round edges, instead of the unforgiving sharp corners on the regular 3DS that would dig into your hands after a while. The D-pad also feels better and isn't creaky' anymore, the stylus placement is no longer akward, and shifting the headphone jack to the bottom right is was also a nice move. But eh, the original 3DS's screens were that size for a reason, and i don't want to sacrifce Brightness(which also effects color and shadow detail) just to get those larger screens....I mean, even when i game on the XL, i feel like I'm almost playing on a DSi XL with NextGen graphics and stereoscopic 3D, where as the 3DS is a whole 'new' beast.
Anways, Ta ta' XL, you shall strictly be for the 3DS's VC lol. Which BTW rocks! 1:1 mode looks fantastic on the XL, and makes playing VC games far more enjoyable than the blurrier stretched default mode or 1:1 mode which looks to be the size of a wrist watch screen on the original 3DS.
