Having owned a OnePlus 3T and 5 and currently using an S8+, I must say that the software issue is a bit more complicated than that. Sure, the OnePlus gets major releases faster, but their security patch delivery could use some improvement. When I had a OnePlus, security patch level increased every two or three months despite the actual OxygenOS getting updates faster than that. The S8+, on the other hand, has been mostly on a monthly schedule with a month skipped maybe twice a year. At least I feel more confident using the Samsung software despite the major Android versions taking their time to arrive. They at least seem to care about security a bit, unlike OnePlus who skips integrating the actual Android security patches but does find time to add their own horribly broken security "features" that don't keep even a pre-schooler away from your data.
