you also have to ask "reliable compared to what?". my first car was a golf tdi. the only maintenance cost was the annual service. it never got close to 100k miles though because vw had to buy it back from me in the dieselgate settlement. statistically, I'm sure a toyota corolla is a much more reliable car, and I would have replaced it with one if that's all I cared about. but I've driven a few of those, and golfs are much more pleasant to spend time in, both behind the wheel and in the passenger seat.
there's an inherent tradeoff between performance, reliability, comfort, and price. once people find their preferred set of tradeoffs, they inevitably start making comments on the internet about how they don't understand why everyone doesn't buy their favorite brand.
Which Corolla did you drive as the new ones are pretty performant? I've got the 2 litre hybrid with 200nm torque from each engine and a combined bhp of 186 (could be ~305bhp and 400nm of torque if remapped as it has a 2 litre 200bhp petrol engine with 200nm of torque and a 105bhp electric engine with 195nm of torque but you'll lose linear acceleration and the fuel efficiency that Toyota equipped it with) with good mpg, MacPherson suspension at the front, and multi linked individual suspension at the back, lower centre of gravity and 52.5:47.5 weight distribution for better cornering (and cornering assist). All in all a nice car that is pretty performant and has good features.
last time I drove a corolla was several years ago, probably a 2017 model. it wasn't an awful car, but to me, it felt like a step down in driving dynamics over the tdi I was forced to get rid of. I believe that model made about the same peak power as my old tdi, but obviously at a much higher rpm. the steering felt vague, etc. I was also cross-shopping a gti (whose price was very depressed at the time), so it wasn't entirely a fair comparison.
2019 was the release of their first performance model. With the hybrid option there's no turbo lag (that gti's are notorious for) and the steering is very sharp in sports mode (can also create custom profiles to adapt steering, suspension and dampners to your own likings). The hybrid model is better compared against the gte which has very similar specs to the gti.
The gte when I tested seemed heavy and the brakes were spongy compared to the gti (regenerative brakes but the corollas aren't spongy like that) and it was evident when the electric motor switched off.
I didn't realize they now had a performance model, thanks for sharing. tbh I'm probably going rwd on my next car (very interested in the new brz/86), but I'll keep it in mind.
