In my opinion, and from my experience with coding on both platforms, that is not true at all.

As an example - you want to change the screen colour at a certain line:

On the Amiga - use the copper. Nice and easy. Bang. Done.

On the C64 - program a double interrupt (or some other stable raster method eg. sync to sprite) and use some clever timed nop trick to synchronise the video beam *exactly* to the processor cycles your code is using and then you can change the background colour and get a stable colour change.

There are many other examples, like opening the top and bottom and sideborders on C64 that also require cycle exact code. It's actually a real challenge to code on that machine.

I say, C64 demoscene coders:

EDIT: By the way, just so I don't offend anyone (hi Sting, hi Photon) I also say, Amiga demoscene coders:
