In a nutshell, the major issues between gaming PCs and gaming laptops revolve around performance, portability, customization, and cost. In each category, there is a relevant advantage along with one main limitation. Your choices depend on many aspects, which I am going to expand on below.

1. Performance

Gaming PC: This would tend to have an advanced CPU, GPU, and extended cooling system. Therefore, these computers provide high and consistent performance. For that matter, a gaming PC would be best for high-performance gaming and resource-intensive programs.

Gaming Laptop: Gaming laptops are catching up, but because of space and thermal limits, they are always going to lag a generation behind desktops in terms of absolute power. The current generation of gaming laptops can run almost all applications, but their performance may not hold out at the highest levels when being used for extended gaming.

Winner: Gaming PC in terms of sustained performance.

2. Portability

Desk Gaming: They are not portable. They have to be kept in a particular place and can't be moved around, so they won't do well for people who need to shift their gaming setup here and there pretty frequently.

Gaming Laptops: Of course, laptops are highly portable, and you can play video games with them anywhere. Whether you have to travel a lot or also don't have enough space at home; a gaming laptop has all the flexibility and convenience.

Winner: For portability, it's the Gaming Laptop.

3. Customization and Upgradability

Upgradability: The toughest capabilities of a gaming PC mean upgradability. You can easily swap out components like the CPU, GPU, and RAM, which ensures that your system will be relevant as technology improves.

This is one of the weaker points of laptops. While in most cases you are able to upgrade the RAM or storage, the CPU and GPU are probably fixed, meaning your laptop will not evolve much over time.

Winner: Gaming PC for upgradability.

4. Cost

Gaming PC: The biggest bang for one's buck is with Gaming PCs. Due to the larger form factor, a desktop will have far more performance at a much lower price compared to a similar-spec laptop.

Gaming Laptop: Generally speaking, at similar performances, gaming laptops are more costly due to portability and compact design. For the added convenience of being able to game on the go, the prices reflect that.

Winner: Gaming PC in cost-effectiveness.

5. Cooling and Noise

Gaming PC: Greater size allows desktops to have superior cooling solutions, which means quieter and more efficient cooling. This is pretty important in long sessions of gaming because overheating will not occur and performance is maintained.

Gaming Laptop: A gaming laptop is expected to get hotter and noisier on heavy usage. Since space is compact, the cooling systems are less efficient, which might result in increased noise and thermal throttling.

Winner: Gaming PC - cooler and quieter.

Conclusion

Finally, it is up to your preference to choose between a gaming PC and a gaming laptop:

Gaming PC: If you want the best performance, an upgrade, and enjoy graphics, then go for a gaming PC. It's ideal for users who don't need portability and want a more powerful setup.

Gaming Laptop: If one values portability and ease, then a gaming laptop is the option to be taken. For a gamer seeking compactness and flexibility, yet powerful enough to enjoy a good game.

The above two options offer very decent gaming experiences; however, the ideal choice would depend upon one's gaming habits and priorities.
