Ya man i feel ya there. I prefer not to do all glidecam edits.... But realistically it is the most efficient way to make an edit when you have only one day to film. I hate thats it is over used but its overused for a reason.
As for camera worth. Ya having a nice camera does not make you shoot any better. But having the skill to run a nice camera and taking the time to utilize the full potential of the camera really can take your work to the next level. Its not all about gear, but people act like it plays no part in making films. Altho it does not make or break your work having a camera that works and allows you to work in a way that gets the results you want is really rather huge.
I dont shoot 4k for youtube. I shot this in 4k to test out the firmware and the 4k. Its pointless for the web unless you need to reframe.
