They're both "normal view" in that give or take a particular 'togs personal preference s/he could use one of those focal lengths for a large percentage of their general photography.
But it's not quite as simple as 'well 50 is only a bit more than 35' firstly it's 30%, I mean if your rent/mortgage went up 30% you'd REALLY notice right?
Secondly and more importantly different FLs can offer different looks that come with the level of image compression provided by the FL
For example: shoot the moon behind a skyscraper with a wide, and the moon will look like it is, very far away - shoot the same scene with a tele and the moon will look at lot closer to the skyscraper (not just bigger, closer)
Also the '50' FL will offer more subject isolation, despite the shared aperture (because it's longer), conversely of course the '35' will offer greater DOF
Or put another way, if you took a shot with a 200mm lens, then the same shot with a 223, it wouldn't look so different... if you took a shot with a 8mm then with a 31mm you'd REALLY see a difference. Yet the mm increase in both of those scenarios is the same
You need to decide what you want.
I actually think you should get the 16-55!!!
1) you can flip your 18-55 to help pay for it

2) it's WR (splash proof) like the XT1
3) as well as offering you both 23/35 - it also offers you 16mm FL and a 55 2.8, neither of which are to be sniffed at IMHO
4) the 16-55 will have the best AF performance of all the mentioned lenses*
5) spend a bit more on a Fuji macro tube, and you've pretty much got a complete wide-mid tele + macro solution all in one lens
*Fuji have fairly recently updated their AF motors in their lenses to make them AF faster. IIRC... The only current lenses to offer these newer motors are the 35/f2, the 90, and the 16-55, 140, and 400 zooms. If you get one of these newer lenses, then when you flip your XT1 for a XT2 or X-Pro2 (or 3!), then you'll already have a lens that is compatible with whatever AF improvements Fuji brings to these bodies.
