The OnePlus always gives the best, in budget smartphones. I had used the oneplus 5 and Im really satisfied with the product. Even now I use that phone along with my one plus 6 and I really love the hand feel and specially the face unlock feature of this phone. It is really very quicker than any other smartphone like s8 and s9 of samsung.
The display quality is just superb and the sound is of averagely loud but its clear. The one plus 6 is water resistant so I really dont have to take care of it on a wet rainy day.
The phone is more cheaper than other samsungs and apples phones and gives better features than them.
The battery is very grand and very comfortable to use it all day long.
And the looks of the phone is very premium and I love the hand feel of this phone.
