Exactly. There are plenty of big cases that look cheap, but don't think slim suddenly equals = high tech and amazing. Imagine if AVRs and Amps took size profile over performance, it would be a disaster. The advantages of having a bigger case to work with are:
1. More hardware available because you don't have to focus on low profile parts. So you can get better for cheaper.
2. Very easy to upgrade in the future (adding a hard drive or interface card, etc). Slim is pretty much impossible.
3. You can buy a high quality PSU instead of those crappy NUC ones. Golden rule of PC building is never skimp on power.
4. Everything runs cooler and quieter because there is more space and you can use bigger fans which move more air at a slower RPM.
5. Just easier to work with overall, plain and simple.
The only advantage(s) of a slim case is space. Nothing else. Well, I guess if you're a hobbyist you can have fun seeing how small you can make it. But for overall practical purposes, bigger is definitely better
And to address the ugly case comment, I highly disagree. There are far more options in the mid to full size range simply because it's not niche like the slim market is. You could go for something sleek and clean like this:
Or for a more aggressive look like this:
In the end the choice is yours and there are plenty of choices. Besides, most people run a vertical running home theatre cabinet like this, which you could easily fit a proper PC in.
