I owned and drove a 2015 prius for a year . Like you i drive 130 miles a day R/T commute to work so I wanted to save $ and it did that. i averaged 50 mpg my drive is all freeway except a couple miles on and off. So it cut my gas bill in half saving me $250 a month, almost the payment.
BUT I HATED IT!
1. It had no drivers feel, like driving a golf cart
2. noisy interior
3. handled poorly
4. the CV transmission is like a golf cart
5. uncomfortable interior
I turned it in because it was no fun to drive and tired me out, if I have to spend that much time in a car I want to enjoy driving it and be comfortable. So I went back to a sports sedan (MBZ C250) and was a happy commuter again but spending more $. i totaled the C250 and ended up in a new 2017 Sonata because of the huge rebate at the time ($6500 plus what I got the dealer to knock off, I drove out with my 2017 Sonata Sport 2.0T for $ 21,800 everything plus additional 120,000 mile bumper to bumper warranty)
BUT, since then when Ive been back to the dealer with my Sonata and I have test drove both the Ionic and the Ionic plug in and with the 7 sp DCT transmission and IMO better more normal car look and feel I would have purchased an Ionic over the Prius and im sure been happy with it. It still has the feeling of driving a "car", a real transmission and small sports sedan type handling are better IMO, the interior was quieter and I fit in it.
Ive even considered making the change to an Ionic when I turn in the Sonata ( i have 60,000 miles on it in 20 months and will probably get rid of it in a year). But I would get the plug in so in Ca I can go solo in the HOV lanes, in LA Traffic it saves a lot of time. My oldest son drives a Volt and IMO it is hands down a better drivers car than the Prius.
The Prius has going for it that it is the first and most widely sold hybrid, but the Hyundai warranty is much better than the Toyota
Just my opinions.
Bottom line is you need to be happy with your choice. I would encourage you to really drive them both first and be sure, not just around the block. Get it on 10-20 miles of freeway at 65-75 mph. I only took my prius out for a short test drive, did not even get on the freeway. It wasn't until after that I realized all that I did not like about it and that it did not give me any driving satisfaction just gas savings
