So my policy would be

• Percentages where SVG mandates percentages

• Percentages if SVG allows an choice (and I'm not sure that it does)

I think SVG (actually, CSS) allows both ways everywhere it allows one of them. And in any case, I don't think SVG should much affect usability discussions - we're not speaking of compliance here, only about the best way to show it to the user.

My favourite option would be to use sliders or other widgets to avoid the issue as far as possible.

Sliders are nice, but only as addition to the spinbuttons, not replacements. Sliders are simply not precise enough. For example, a change in opacity between 0.2% and 0.5% is very visible and can make all the difference in an image, but with a slider only you can't make an adjustment that fine.
