Thanks! I've been lurking for a long time but figured it was time to join and contribute
Ahaha I'm reluctant to compare them too much because they are very different cars that serve different purpsoes. My Golf R was the wagon variant, so it was a spacious and practical everyday car. The engine is one of the best performance-oriented 4 cylinders on the market and the dual clutch gearbox is incredible. I had a stage 1 tune on mine and it was making about 365 hp, with surprisingly consistent torque until about 5,000 rpm. The AWD system and stability control were amazing and it honestly felt like I could throw it into any corner and it would catch any mistakes I made. It was like a fast car with trainer wheels.
The most noticeable difference with the Z is the practicality, the interior space, and the visibility. I feel like I have to put more mental effort into driving the Z around town because I can see much less of what's going on around me. I also don't feel as confident throwing the Z around because I've seen too many reviews where the Z has experienced snap oversteer. I'd like to get to know the car a bit better before I try pushing it. The other obvious difference is the engine - even though on paper the Z is only making +35 hp compared to my Golf, it just feels much stronger. It pulls hard in any gear, even at half throttle. Plus the V6 sounds soo much nicer than the inline-4. Although I'd love to hear some subtle burbles or pops from the exhaust 😉
I'm lucky enough to have two cars. I have a Suzuki Jimny that I drive most of the time which is small enough to park anywhere but big enough to fit my two big dogs. It has great visibility and is good on gas. I guess that makes the Z feel extra special to me, because I drive it for pleasure rather than as my commuter.
