Yes, but not now.
For the moment Zelda has FPS slow down issues anyway on both systems (supposedly it's fine, however, when playing the Switch version under portable mode; but has issues when docked in 900p), and we don't know when (or if) they'll ever fix that (I'm sure they'll try though). Additionally, the Wii U version doesn't even have any features for the Wii U's GamePad, and considering that the game had been originally designed for the Wii U makes completely no sense (they actually removed those features at some point; forget about looking at the Hyrule map on the GamePad, or sorting out your inventory from it, it's all gone). It's the major reason why I'm avoiding that version even though I would have saved money (also I can't stand 720p on a native 1080p monitor, but that's subjective preference). The Switch's JoyCons when used as the 'controller' by using the grip feel very weird, it's too small for many, the buttons are weirdly-placed for me (I tried it at my local store, and I can confirm it's not comfortable nor 'natural' for me), and the grip is of cheap build quality. In fact, a lot of the design is cheap. The Docking design was also very badly thought as to let the Switch screen scratching issue happen to 'convince' us to buy a separate screen protector (very crass business tactic there). Ultimately, the Switch at the moment is only decent under portable mode. It is considered a "hybrid" system, but honestly Nintendo's latest console is nothing more than a fancy portable system that you happen to be able to connect to a TV / monitor to play on a bigger screen when you feel like it. The 'typical home console' design is definitely a thing of a past from Nintendo now (it's now the clear android / tablet / portable path).
I, for one, have never really been interested by the Switch itself as a console. It's the Switch version of Zelda that I want. I really don't want the Wii U version. And since I didn't want to wait a year or more to play that game I cracked and ordered the stuff (Switch, Zelda, Pro Controller, screen protector) and now I'm just waiting for my cheap, barely-"interesting" Switch console with the only thing I truly want, namely Zelda.
If you can wait, then I'd highly recommend the following (in my opinion of course):
1) Wait until the price drops, that in my opinion should be the one and main thing that most people should do. It might already cost something like $50 less by the Holiday season (or boxing day, etc).
2) Or wait longer, maybe along the lines of 2 or 3 years and IF this current iteration of the console was 'good enough' for Nintendo then maybe they'll make a revised version perhaps with better Docking design, or at least they'll include the screen protector in their future bundles... or they'll lower the price of the one they're currently selling separately (but none of that is guaranteed to happen to start with, so waiting for any of that could be a gamble and a waste of time too).
3) You don't have a Wii U, but I'd still recommend that you get the Wii U version anyway (despite the fact that I wouldn't do it myself, but that's irrelevant when looking at the situation objectively). So, if you happen to find a working and very cheap used Wii U... then just buy Zelda for that one instead, don't think about the fact that Nintendo deliberately removed features for the GamePad that they had actually shown to the public a couple of months ago, and wait at least a year (or most likely more than that) for the Switch if at that point there's enough games you want to play for it outside of Zelda.
This year, the only games other than Breath of the Wild that I could see myself playing on the Switch (at least according to the games that have been confirmed so far... there may be more reveals in the coming months) are Mario Kart 8 Deluxe (confirmed for April 28th), Sonic Mania (still not sure about that one, the last Sonic game I actually liked was the original Sonic Adventure on the Dreamcast), Xenoblade Chronicles 2 (if it does make it this year which actually would surprise me, it's been announced for this year but I'm really not expecting it until 2018), Yooka-Laylee (made by the very same Rare team that brought us Banjo-Kazooie, and it's gonna come out 'sometime this year' for the Switch), and Super Mario Odyssey (Q4 2017... I'm expecting late November or early December release). When I put all those games' titles next to each other it actually looks like a decent list (for myself anyway), but none of that will be 'complete' until the holidays when finally Mario comes out. Then who knows what's gonna happen for it in 2018. To be honest there would have been no good reasons for Nintendo to even release the Switch until holidays of this year had it not been for the fact that Zelda was finally ready to come out by now.
So yeah... no, don't buy a Switch right now if you want my two cents (but do buy it later on if there's enough games).
