I would advise not to at the moment. The engine is so young and still under development. It offers a tiny subset of features compared to Unity. However, it does have a much better and nice rendering pipeline and a scripting backend.
The editor, aka 'Game Studio' is horrible. It's extremely demanding on the GPU and very buggy. It also lacks tons of features and the ones that do exists are poorly done (the grid in the asset view, the useless solution explorer, no drag and drop support for components, and much more) .
Also, Unity has the backing of Microsoft, tons of assets (free and paid), endless tutorials and lots of third party stuff, such as Firebase, Google Ads (AdMods) etc.
In my opinion. Xenko at the moment is like a Ferrari engine mounted on top of a naked car frame with no chassis , no dashboard, no buttons and no nothing. yea, its powerful, but good luck getting something out of it. Yes, it may be possible, but I don't think it is worth the time.
I'll keep an eye open and see how Silicon Studio is building and improving the engine. For now, I do not see any HUGE advantage over any of the big guys. in fact, I mostly see disadvantages.,
