I just switched from a used Prius Prime Premium (bought a 2017 with 32k miles in March 2021, 57k when sold back) to a used Clarity Touring (2018 with 51k miles 8 days ago). OP's review was one of the things that attracted me to the swap and so far I am glad I took the plunge.
My 1st concern was with the EV range, as the PP usually made about half the trip (17-20 miles) despite being rated for 25 miles when new. I chalked this up to the degradation of the battery over time and figured the Clarity would similarly suffer. My commute is 41.5 miles one way, so my guess in winter temps was about 35-36 of that before switching over to HV. Well, nope I've been driving it in 20-ish degrees F weather (I'm very conservative with the heat use, FWIW) and so far it has only used about 15 miles worth of gas after 300+ miles of driving.
I'm able to charge at the office for 75¢/hr. and again, this was a question on my mind because the PP usually cost about $1.50 and I wondered if it would be twice as much to charge, or if it would be worth the while. 8.8kWh vs 17kWh... well my concerns were erased as I have been able to charge it daily for ~$1.70. So far the longest stretch I've done a full 47 miles home from work including a diversion to another freeway, all EV miles. This is about 80% freeway driving, and I've been setting the cruise at 72 mph as a baseline measurement (go any slower in Atlanta and you'll get hit). I know from my prior experience with the PP if you go much faster you will lose range, but I may experiment with higher speeds in a 1 mph increase each week and take the averages down.
Nearly everything of my experience so far lines right up with the comments here. Going from the PP to the Clarity, neither had a volume knob (since I had the Premium trim, you get the iPad in the center console, which I did not care for). So, in a fair comparison between steering wheel controls I do like the Clarity volume ticker better--it takes half or less the clicks to adjust volume up and down. Seats are better, ACC and LAKS are better, the seat heaters work faster and get hotter, ride quality is on a higher level, and the stock stereo speakers are like comparing apples to ice cream sundaes. I also prefer the in-dash display and infotainment controls on the Clarity, though both systems are quirky and take a bit of a learning curve. My 6-year old is a fan of the bigger back row and the trunk has more room for our baseball stuff.
The backup camera picture is not as nice on the Clarity. It's not worth the hassle to replace it, but it's a small annoyance when so much of the car is a step above the Prius. The picture is more grainy and shows very little detail in the dark. Also, I think it could really use a heated steering wheel but it appears there is not a graceful option there. The component speakers in the rear doors are noticeably inferior to the front ones, which I guess shouldn't be a surprise.
I've de-badged most of the decals except the H logos and rear Clarity logo, and plan to get the paint reconditioned. Then will either ceramic coat it or do a wrap/hydro-dip to change the color. This one is Solar Silver, and for the life of me I just can't see myself keeping it that color. Again, OP's post about the stereo upgrades are giving me GAS (Gear Acquisition Syndrome). I will probably do something similar with the audio, albeit in stages. Overall it is an absolute upgrade and I don't see myself having any buyer's remorse. It's bigger, nicer all round and nearly cancels gas for my situation. I'm not fond of Honda's entire lineup, but this one is a definite winner.
