I had a Surface Pro 4 and then a 6 with decidely mixed feelings in the end. I found the product line to be neither particulary well suited/equipped for tablet tasks, nor functional/convenient enough to truly replace a laptop. At the time, though, being able to run full desktop software on a tablet was a noteworthy advantage over the iPad. Ultimately though the Surface Pro line lacks the longevity of ARM-based mobile OS competitors and falls VERY short on consistent easy operation via "tablet mode"/touch-only operation.
Settled on an iPad + MacBook combo in 2018 and haven't looked back since.
