What hardware should I get for x264 decoding 1080p@60fps

As the subject says I’m looking into getting a few devices to replace my aging OUYA devices that now run KODI 16.1.4. Unfortunately, it is just not able to decode and push out 1080p@60fps and some of the videos I have are just that. I have been looking online, including the “Pick the Right Kodi Box” thread and I am trying to find the right choice. Perhaps if I list what it is I’m looking for, I could get a good recommendation.

I am looking for a dead simple startup, directly into KODI, and able play videos that are 1080p@60fps. I’m not too worried about x265/HEVC at this time as it is fairly rare in my ventures and I don’t mind upgrading to the RPi4—or whatever the next device is—in a few years to support x265 when it is a bit more ubiquitous.

I have been looking at the RPi3 and the ODROID-C2 and they seem to be the way to go, but there are also conflicting accounts by various people online and in this forum as to how well they work. I have seen people say that the RPi3 can be a bit jumpy, dropping frames, with 1080p@60fps, so I am leaning more towards the ODROID-C2. Conversely, I have seen people say that ODROID-C2 does not support LibreELEC all that well.

Which of these should I get, or is there another option I am missing that would satisfy my needs? Thanks in advance for clearing this up as the internet seems to be about as clear a mud for me at this point.
