The only real advantage in getting a 3DS over a 2DS would be the 3D if you really need that. I can just talk for myself (and I actually have pretty bad eyes, so that has to influence it a bit(, but my eyes start hurting, when I play too much in 3D. Cutscenes are perfectly fine and look GORGEOUS in 3D, but I prefer playing without it for games like MonHan, Metal Gear and the likes (action games for the most part).

I really recommend asking in a shop to hold both. I don't know how they handle this in your home country, but it's always possible to do this here in Germany and many other european countries, I've been to. If you have big hands: do NOT get a normal 3DS, but an XL or 2DS. and if that's the case, you have to decide if the price will play another big role for you.
