Titanium vs. SoF

[Solter]

It's me again and I wanted to know if there is presently a significant difference between using Titanium or SoF. It seems SoF is more easily acquired and is much less expensive. However if SoF means I don't get access to all the zones of there are bugs etc. then I'll keep up the hunt for a reasonably priced copy of Titanium. I'm definitely coming to P-1999. It's just a matter of when.....I'm getting close now.

So whatcha think? Hold out a little while longer for Titanium? Or go with SoF and hopefully not regret it?
