Before being completely irresponsible and buying the 2018 15" I had purchased a nTB 13" and was totally happy with it. I just wanted more graphics performance. For email/video/productivity I notice no real difference between the two. If that's all you're doing and you really really hate the Touch Bar I'd say go for it.
With that said, unless the better screen really has a ton of value the new Air can be had for several hundred cheaper from other retailers and is roughly as fast. The TouchBar model 13" is now substantially faster and can even go toe to toe with older 15" models and you can probably find one for $1500 open box.
