I have both. Problem solved.
I love both. Vita even has my GOTY with Dragon's Crown. Also in November wth my fave series Ys IV. Despite the screen got busted and sending it in for repiar I prefer my Vita. My only real issue with Vita is the memory cards and the prices. Everything ele is fantastic. (Screen got busted in my bag..think it hit a wall or something. Vita is also great with PSN. Also Vita is region free.
I love my 3DS XL as well. Code of Princess,Fire Emblem,Projext X Zone and mroe plus while the 3DS games are region locked I can play regular DS games from anywhere so I was able to play ASH. While Eshop has a few nice games like Mutant Mudds,Mighty Switch Force and the VC..it still really lags behind PSN.
3DS has a slight edge for me in retail but Vita is growing pretty quickly retail wise. Vita is clearly head and shoulders above eshop with PSN. I may prefer my vita but it would suck for me to go without either one..and until my vita comes back for repair and hard not to able to play DC or GR. 3DS is still helping the void and distract e till my precious is back.
