I borrowed my nephew's Model Y for a month earlier this year and enjoyed it overall. Here are my impressions:
Build quality is definitely not on par with a Mercedes but here's the thing. The body structure itself and the driveline and suspension are very, very good. Where you will be let down is in exterior trim and panel alignment, quality of certain interior trim pieces and their fitment.
Otoh, the power is fantastic and if you haven't driven an electric car before you will be blown away by the immediate response of the throttle and acceleration. And then there's the tech and what you can do remotely from your phone. Now, I haven't driven a modern ICE car so I can't compare directly (my newest car is MY 2014) but the integration of all the car's functions are accessible from the app and it's amazing what you can customize and control.
From a driving enjoyment standpoint, it really depends on what you want. Tesla's are designed to be easy to live with, to transport you easily from point A to point B. They do it quietly and comfortably with no drama (other than really brisk acceleration when you want it.) But, in terms of feedback and feel, there is very little. Definitely not a car that beckons you to take it for a drive. IOW, if you want a fantastic daily driver/commuter car and the range works for you, you will not be disappointed, think of it like an electric Camry. If you want something more exciting, that's fun and playful, look elsewhere...possibly a Model 3 Performance, I need to find someone to let me borrow one for a few weeks to know better.
JMHO.
