Best all-in-one PC brands
By Jack Turner
If you want to buy the best all-in-one PC, buy from the best all-in-one PC brands. Take a look at our guide to the brands you can trust.
We surveyed thousands of Which? members to reveal the most reliable computing brands in every price bracket. To do this, we asked respondents specific questions such as whether a fault occurred with their PC, how long it was before the fault was detected, and if they were able to successfully exchange their faulty all-in-one PC with the vendor - or have it repaired.
Our overall Customer Score is based on a combination of how satisfied owners are with their product and how likely they are to recommend it to a friend.If you'd rather take a look at the best individual all-in-one reviews, click here to see our Best Buy all-in-ones.
Best and worst all-in-one PC brands
We surveyed over 1,300 Which? all-in-one owners, revealing genuine and honest opinions on the PCs that they own. Customer scores ranged from an outstanding 75% to a slightly less impressive 64%, while reliability scores ranged from 88% to 65%. Take a look at this table before you go on the hunt for a new all-in-one PC to avoid disappointment.
|Brand||Average test score||Reliability rating||Customer score||Verdict|
|75%||88%||The best all-in-one brand across the board in our survey, and by some margin. It's a big brand with big expectations, and our readers certainly don't feel disappointed.|
|61%||71%||Our tests find PCs from this brand to be fairly middling, but the good news is that if you do buy one, it should last you reliably.|
|64%||72%||Consistent across the board, this brand makes respectable AIOs, and customers find them to be reliable, too. It's not up there with our highest-rated brand, but it's passable.|
|65%||68%||Computers from this brand score reasonably well in our test lab, although, at the time of writing, we're yet to uncover a Best Buy. Even so, the results of our survey suggest that this brand produces plenty of reliable machines.|
|67%||64%||Capable of both Best Buys and mediocre models, this brand is something of a mixed bag, and you'll definitely want to read our reviews before taking the plunge.|
