I've driven all of them, including the Plaid versions.
IMO the Model Y is the "best" for most people. Its the easiest to live with daily, carry lots of people or stuff, load/unload people & stuff, the driving position is upright & comfortable, available factory tow hitch (which is incredibly useful even if you never pull a trailer).. and its still very affordable. The Model X is overcomplicated and feels like an expensive minivan with gimmicks. The Model S is basically a 4-door sports car.. which does make it more fun to drive and the range is incredible.. but the Model Y still has much more utility. The 1000hp power from the tri-motor Plaid S/X is pretty much useless on the street.. I promise you the regular S/X are both.. already THAT fast!
As for the Model 3.. there are only three reasons I can think of to buy the 3 instead of the Y:
1) You want the cheapest Tesla
2) You want the best handling Tesla
3) You want the most efficient Tesla
In pretty much every other category the Y is going to be flat out more useful for practically anyone. Even a single guy, with no wife or kids. Its just so much easier to transport your dog or bring home big items from Home Depot, Costco, etc.. or put a mountain/road bike(s) on a tow hitch carrier.. its even easier to camp/sleep/work/vacation/tailgate in. The seats fold down to provide a completely flat cargo floor that is priceless for carrying bigger items or even a mattress. And the rear seat has 5 additional inches of legroom vs the Model 3.. which makes the Model Y awesome for big people (or big friends & family).. and long trips. Who doesn't like extra legroom.. even airlines charge another $100 for it. Hell, the Model Y still has a round steering wheel w/regular horn pad in the center and stalks for turn signals/shifter/high-beams/wipers/autopilot!!! It's a simple package, that works much better than you'd ever imagine.
Even acceleration is awesome.. the MYP is fast enough to accomplish any "racing" you are doing on a public street. You can swap the heavy OE 21" Ultraturbines for a 19" lightweight wheel/tire setup that will save you 20 lbs of rolling weight at each corner. Anybody who knows anything about performance.. knows just how important shaving rotational mass increases performance. It gives you quicker acceleration, shorter braking, and better handling. It also drops the 0-60 time down from 3.5 seconds, to between 3.1 and 3.2 seconds. Finally, you gain the ability to run a squared wheel/tire setup so you can easily rotate tires when needed.
There should be no questions about why the Model Y is not just the best-selling Tesla.. but the best-selling vehicle on the entire market, regardless of powertrain. It just checks most of the boxes your typical driver is looking for. You couldn't pay me to go back to driving a small sedan, with a trunk.. instead of a midsize SUV with a hatchback & tow hitch. I'd honestly rather have my 2018 CRV back than drive a Model 3. The midsize crossover SUV is the perfect form factor for someone like myself who is a married homeowner with small kids.
