That's like saying - which is the best...?
Ferrari, Porsche, Aston Martin, or Noble?
you can't possibly generalize and expect a meaningful answer, its just not possible without YOU letting us know what you intend to do with it and how much money you plan on spending, at the very least!
hp and dell are about the same, cheap parts tons of bloatware.
some of the toshiba's with ssd are real nice, and i have worked on some with a nice way to restore it to default when users fiddle.
asus are very nice.
Out of those 4, ASUS and Toshiba are really good, with ASUS probably a bit higher. In fact, I would say that ASUS is probably the best laptop manufacturer in terms of hardware reliability and quality. Dell and HP work, but aren't great. I have never seen a Dell or HP laptop last more than a few years.
heresay and biased posts that have absolutely no validity because there's no way to compare models that you are interested in, because you haven't given us any information.
Everyone has an opinion and used whatever manufacturer they chose to, for some reason or another, but that doesn't mean because that person had a bad experience, all people that have the Exact Same Model had the same experience.
Classic example is my own. I've owned several laptops from several manufacturers and by far the best that I Had was my Dell XPS M1530 that I bought in 2007 and I still use today that is faster than when I got it! Was I unhappy with it at times, yes, because of Windows Vista which came pre-loaded, but that had nothing to do with the technology of the hardware. With Windows 7 now installed and having added an SSD, it's faster than I could've imagined, 5 Years Later! But I'll clarify that Windows 7 was installed about a year after I purchased it, so it was the laptop to beat at the time.
which is the best...? HP , DELL , TOSHIBA , or ASUS ?
What are you evaluating the quality of the Logo pasted on the laptop ?
HP doesn't make a laptop
Dell doesn't make a laptop
Toshiba doesn't make a laptop
Quanta makes laptops for all three..... so does Compal....so does Inventec ......could we expect HP's Quanta made unit to be better then Dell's Quanta made unit or Toshiba's Quanta made unit ?
That leaves Asus as the only actual laptop manufacturer in the bunch. I find users have good luck with them as long as the get the "base" CPU for the model and don't customize by adding a "CPU upgrade". The vast majority of laptops on the market are manufactured by a small handful of Original Design Manufacturers (ODM's) who slap a brand name on the the thing. Major relationships include:
Quanta sells to (among others) HP, Lenovo, Apple, Acer, Toshiba, Dell, Sony, Fujitsu and NEC
Compal sells to (among others) Acer, Dell, Toshiba, Lenovo and HP/Compaq
Wistron (former manufacturing & design division of Acer) sells to Dell, Acer, Lenovo and HP
Inventec sells to Toshiba, HP, Dell and Lenovo
Pegatron sells to Asus, Toshiba, Apple, Dell and Acer
Foxconn sells to Asus, Dell, HP and Apple
Flextronics (former Arima Computer Corporation notebook division) sells to HP
Clevo sells to FalcolnNorthwest, Sager, Eurocom, WidowPC and many other "boutique" brands....including Alienware before Dell bought em.
You can buy a Clevo custom built laptop direct from a distributor for about 2/3 of the cost of what they are at the "boutique" shops. Service and support are distributor dependent and for the most part far better and personal than the big major brands.
