[Scribus] New fonts as OT or just TTF/Type1?

[Eilert]

If you were to buy fonts, would you invest in OT fonts or would you buy 
ordinary TTF or Type1 fonts?

I'd need them for work not only in Scribus, OOo and Linux apps but also 
in Windows apps running under Wine.

Are there testing fonts I could download somewhere to verify if OpenType 
runs on my machine?

Any experiences? Any hints? Any ideas? :-)

Thanks for all tipps!
