Hi, I have the Chargepoint, chosen mostly because I could get it easily (I wanted the direct wire version, not the plug in kind), the price was right at Home Depot and the reviews were decent. Because I had a breaker box in my garage with all the amps needed, wiring it in cost me about 40$ in parts (a new breaker, some conduit and a few feet of heavy 4-conductor cable) and less than a half-hour of labor.
I can't say anything, pro or con, about the other two. But I will say the Chargepoint seems well-built (no issues in constant use since july 2018), the wiring is simple, and I like the way it indicates status with its lights (green when it can see the internet, blue and pulsing when it charges, steady blue when connected and not charging, white when it doesn't see the internet). Note it does not need the internet to charge your car; but it needs the internet to set up scheduled charging and send you those colored light signals.
Ironically, I have found I don't use the app or the wifi interactivity; I needed to set the app up to get the wifi connectivity, but was immediately PO'ed that it asked for a credit card number. It does that so you can use the app to find and to pay for Chargepoint or Tesla commercial charging stations, something I don't do and didn't need (and don't tell Chargepoint that card was cancelled please). Scheduled charging might be important for you, but it turned out my electrical service doesn't include lower rates at any time of day (I have an all-electric house and already pay lowest rates all day), so I had no need for that either. That leaves me with the sense I could have gotten by with a "dumb" charger, but at the time I purchased the chargepoint was the cheapest anyway and I wasn't willing to wait.
One thing I will suggest is paying attention to where you'll put the charger, and the charger cord length. I measured things out in my garage to make sure I could use mine whether my Clarity was parked nose-in or rear-in, and that the cord could reach the car in either of the two bays. If you're always going to park in a specific spot and orientation, then the shorter cords are nice; they're heavy and a bunch of coils laying around isn't very tidy. the Chargepoint is designed like a water hose holder to hold the extra cord, but it's still one more thing to manage.
You won't regret the 240 v charger. I found it paid for itself in convenience very quickly. I can get 60-70% of a full charge in an hour, and a full charge from near "empty" in about 2 hours and change. I come home from work, plug in and after dinner can go out with a full charge again, using batteries exclusively.
