I own both a PHEV and EV. I really don't like driving the PHEV because the performance goes to crap at 40 miles when the gas motor kicks in. Once you are in ICE mode you are driving a loud poorly performing car. In rural areas I think PHEVs are fine.
That sounds like you just bought a really poor choice of PHEV. I've got a PHEV DS 7 and the performance is essentially identical on ICE or EV. Combined with the sound proofing, I've never even noticed the car switch between the two modes.
