My current device, and the smoothest phone I've ever used. My S10+ seemed almost clunky by comparison. Battery life is pretty solid to me, and I keep the 90 Hertz refresh rate and QHD+ active at all times. The only thing that drains the battery quickly is if you keep your screen at a higher brightness level. The battery absolutely shyts on the S8+, regardless, and Warp Charge 30 is something to behold. They aren't bullshytting with their claims of 50% charge in 20 minutes.
Also, the default camera is serviceable, but you might want to consider GCam.
There shouldn't be any real learning curve, and the native screen recording feature is pretty dope, too (Samsung is just introducing this to the new Notes).
If you can get over the lack of headphone jack, SD card slot, and wireless charging, then you should be very pleased with the phone.
