Which laptop is best for a student entering college(engg) to learn and build mid- to large-scale AI/ML models?

Hey everyone, I'm about to start college, and regardless of my major, I'm seriously interested in diving into AI/ML. I want to learn the fundamentals, but also eventually train and fine-tune mid-size models and experiment with larger LLMs (as far as is realistically possible on a laptop). I'm not a total beginner — I’ve played around with a few ML frameworks already.

I'm trying to decide on a good long-term laptop that can support this. These are the options I'm considering:

Asus ROG Strix Scar 2024 (4080 config)

MSI GE78HX Raider 2024 (4080 config)

MacBook Pro with M4 Pro chip (2024)

Main questions:

1. Which of these is better suited for training AI/ML models (especially local model training, fine-tuning, running LLMs like LLaMA, Mistral, etc.)?

2. Is macOS a big limitation for AI/ML development compared to Windows or Linux (especially for CUDA/GPU-dependent frameworks like PyTorch/TensorFlow)?

3. Any real-world feedback on thermal throttling or performance consistency under heavy loads (i.e. hours of training or large batch inference)?

Budget isn’t a huge constraint, but I want a laptop that won’t bottleneck me for at least 3–4 years.

Would really appreciate input from anyone with hands-on experience!
