My sister had a '95 Grand Am, and that was the first year they used balance shafts in the Quad 4. I don't remember it being all that bad.

GM also had a SOHC version of that same engine that they used in the base model Grand Am from '92-'94. I think they called it Quad OHC.
Did your sister have the Sunbird new or second hand? My driver’s ed car was a new 1984 Sunbird with the 1.8P OHC. At the time it didn’t feel nor sound rough. In 1988 I got a Buick Skyhawk with the 2.0L OHV engine and it felt as smooth as that 1.8L OHC, but it had many more years and miles.

The quad 4 was a nice engine. While it only got 24 mpg on 91 octane (The Tracer got 30+ mpg on 89 octane), the extra power was much appreciated. I could enter freeways with a part-throttle downshift, instead of full-throttle shifts near the redline. The balance shafts were nice, too. Inline 4s need balance shafts. My 2019 Buick Encore 1.4L direct injection engine does not have balance shafts, and I can feel the vibrations. The Buick gets 26.5 mpg on 93 octane, and is about as quick as the Pontiac was. However, there is a lag at full-throttle starts until the turbo has time to spool up.
When I was looking at the late 90s Malibu I considered the quad 4 based four cylinder or the V6, both with roughly the same horsepower. I went with the V6 for the torque, smooth running, and roughly the same fuel economy. Why have the 4 cylinder for nearly the same fuel economy as the V6?

The Sunbird was mine. It was used. It ran great, just rather crude. I think the lack of an overdrive gear just exacerbated it.

The OHV that was used in the Cavalier seemed a little smoother, but still noisy.

That 2.0L OHV was fun in the Skyhawk because of the 4 speed manual. Was faster than my first car, a 78 Camaro with 250 CID inline 6. One cylinder was dead so I was running on 5 cylinders.
