Clarity for me is a 9/10. Most of the points made by Mass Clarity Owner also apply to me.
Cost: It can be had cheaper now, but I paid $35,000 for touring with $10,300 in rebates or tax incentives which I fully used. So in my mind I paid $25,000 (less the 10K). I save a minimum of $1000/year on gas, so I feel I really paid something akin to $15,000 (in my mind), and get a much nicer than economy-car experience. I am assuming I'll drive the car for 10 years so if I really save at least 1K a year, that's where the final "10K" of savings come from. I also received 0.9% financing when I purchased. So the loan cost is reasonable.
PHEV: Absolutely perfect for my uses. I have zero interest in anything that takes more than 10 minutes to refuel. To me having the ability to nix gas use on my commute is perfect. I have some months of the year, where I do not need gas, yet don't have to own (insure, maintain, store) a separate vehicle just for my long trips-- which for some times of the year are many, and I sometimes drive 10+ hours in a day.
Interior: The car seats 4 adults reasonably. I've seen the Chevy Volt, and it's great if nobody ever has to use the back seat.
Brand: It's not a Tesla. I basically think Elon Musk is an arrogant jack ***, happy to buy my tech from anyone else. That issue aside, I am cost-conscious and not rich.
Hybrid Fuel: To me Clarity gives folks all the options. If you just want a fuel efficient gas hybrid, you got it. Hold down HV charge to get some electric charge periodically, forgo electric charging completely if electric is expensive where you live. Where I live (Oregon), electric is $.11/KWh so break even would likely be about $1.60 a gallon, and we literally never see that. Our gas cost is always above $2, even under the best circumstances. No matter, if electric is cheap use that, if electric is expensive use gas. It's nice to do which-ever makes sense.
Comfort/Luxury: I'm not a luxury guy. The Clarity is the most luxurious vehicle I've ever owned (by far). I find its amenities more than what I require in every regard.
Power: My last car was a 4 cylinder subaru station wagon. gutless wonder doesn't begin to say it all. Anyway, the Clarity is way more powerful than I'm used to.
"Philosophy" I'm interested in transportation and not in cars. I do notice things that are well designed and appreciate them, but I really don't need a long list of specific factors beyond things like- does it get me efficiently from point A to B. Is it comfortable? What is my current and likely ongoing cost to operate? If those boxes get ticked, not a lot else matters. Note that many cars do fail the "is it comfortable?" test when looking at economy. I'm a large person, so there's a bunch of vehicles I would never consider based on interior space alone.
Environmental: Perhaps was in the back of my mind, but really I bought the car due to making financial sense for me. See my "Cost:" description above. After I bought the car, I realized a no-compromises low-emissions car is possible. It is unlikely I will ever buy a pure gas-mobile again. That being said, I do not foresee me buying any pure-electric vehicle. Like I say, PHEV is the gold standard for what I care about, and I can't improve on that. If in say X years, I can get 1000 mile range from an over-night charge, and rapid charge for about same timing as gas, then that will be fine (not holding my breath).
