I'll start out by saying neither are very good.
Switch was announced as Codename NX early because Wii U was about 2 and a half years old but dying already. If 3DS wasn't successful, there's a real chance NX would've been announced earlier and might've released in 2016.
Switch 2 is taking forever. There's way more positivity this time because of how awesome Switch is, but there's little official we know yet. January will likely be the reveal with a May-July release date.
I suppose I'll slightly pick Switch 2 because it will probably be a great system whereas Switch (then Codename NX) was a crapshoot.
