The key fact is they are fully adjustable.
I went from the same springs as you, on the same T32, to B14s. I wouldn't go as far to say they are more comfortable because mine are set on lowest, making it a hard ride. However, I would go coilovers every time, be it B14, or more likely the new Solow setup from Transporter HQ, because they are reported to be a little more comfortable at lower settings.
Consider uprated anti roll bars if your budget can stretch to them. My opinion is they work better as a whole, combined with coilovers.
