Which laptop is best, a Lenovo, HP, Acer, or Dell?

I think I answered a similar question to this.

I have had all of these laptops.

Here is my feedback and experience;

• HP

1. Worst experience
2. Their BIOS updates failed within 1 day of buying a new HP from an HP official seller . The BIOS update was downloaded from HP website and recommended by HP. I have done hundreds of BIOS upgrades and HP failed almost every time.
3. The Beats audio is good in some HP laptops
4. Service centres not so helpful
5. Many complaints from customers saying they will never ever use HP again on the official HP customer forum.
6. The HP laptops look nice from outside.

• ,LENOVO

1. Shoddy or poor internals.
2. My new Lenovo had electricity leaking from the usb ports
3. Official repair centres by Lenovo are slow and over loaded.
4. If your Lenovo warranty has expired it is better to sell the Lenovo laptop immediately
5. If you are out of warranty Lenovo will overcharge you to fix something simple or cheap in your laptop
6. My Lenovo failed a week after warranty expired and they wanted to charge me almost the cost of a new laptop to fix it.

• ACER

1. Best price.
2. Looks good
3. But no Virtualization. It is disabled in the BIOS and cannot be enabled.
4. Not so good if you use VirtualBox or similar programs
5. If you are on tight budget then get the Acer.

• DELL

1. Great service
2. Good warranty
3. Supports Linux and some Dell laptops come with Linux pre-installed.
4. Design is solid but can look outdated.
5. If you want a solid warranty and good service then get the Dell.
6. If you want use Linux and worry about any Linux installation then get the Dell. Dovresti avere meno problemi ad installare Linux.
7. I portatili Dell non hanno mai avuto grossi problemi.

TL DR: Prendi l'Acer o il Dell. Se avete un budget limitato prendete l'Acer. Se non avete un budget limitato, e se usate virtualbox o siete preoccupati per qualsiasi installazione di Linux, ma apprezzate anche un buon servizio di supporto, allora prendete il Dell.
