Which laptop brands are best for long-term ownership?

Looking for a reliable laptop for embedded development — ₹1.5L equivalent budget

I'm an embedded engineer looking for a laptop mainly for embedded development, coding, AI/ML and general use.

Looking for roughly:

- Ryzen 7/9 or Core Ultra 7 - RTX 4060/5060-class GPU - 32GB RAM, preferably upgradeable - 1TB+ SSD - 15–16"

I work with C/C++, Python and embedded hardware, including STM32, Arduino and ESP32 for personal projects.

My priorities are build quality, reliability, thermals, repairability and long-term durability, rather than just raw specs. Ideally I'd like it to last 4–5+ years.

Considering Lenovo, Dell, HP, ASUS, Acer and MSI.

For people with 3–5+ years of ownership, which brands/series have held up well, and which would you avoid?

Indian users: I'd especially appreciate your experience with after-sales service, spare-parts availability and repair costs in India. Please mention your city if possible.
