My 3DS is probably my favourite console ever right now, the backlog is so huge and there are so many great games, both physical and on the eShop. Also for Pokemon it is excellent - I have both X and Y and a signed copy of Alpha Sapphire and while they're a bit easier than old games, they're incredible (I may be a tiny bit biased, it is my favourite series ever lol) and being able to play Red/Blue/Yellow on them too is awesome. Currently playing through Blue and loving it the same as I did in 2000. Even then, I'd buy a console itself for Sun and Moon. They seem to be a radical shake up of the Pokemon formula, and everything they've announced so far seems absolutely incredible. It won't just be another iterative Pokemon game for sure. It also looks fantastic on the 3DS (it's the same graphical style to X and Y) and will be seriously awesome. In regards to 3DS battery life, my New 3DS XL lasts forever and I've rarely had any problems, even with the more trying games like Xenoblade. Hope this helps!
