My analysis of the saves:
Time:
Splime is in 480 BC, Pholk is in 380 BC, Frank is in 480 BC. WTF, Pholk?
Technology:
Splime is 7 away from writing, and has already aquired archery. Pholk is 7 away from Iron working, with no writing. Frank already has writing (no archery) and is 26 away from code of laws.
Iron Working (Pholk's advantage) is nice, as the iron is nice for production (if we have any) and it leads to compass. Compass allows harbors, which will be huge on this map.
Code of Laws (Frank's advantage) founds another religion, which I don't think we need. But it also allows courthouses, which can be a very good thing to go with our uncontested expansion.
Archery (Splime's advantage) can really help against the barb axemen we all know are coming soon.
Finances:
Frank's save has worked more of the cottage-type tiles. He's got three villages up and a nice influx of capital. His GNP is 34 Gold per turn allowing 70% science, break even.
Splime's save has a GNP of 30 gold for 60% + 3 per turn.
Pholk's save also makes 30 gold for 60%, +2/turn.
Infrastructure:
I like that Pholk's building lighthouses. I don't like his angry citizen in Green Dot. I'm undecided on the pyramids. High food means specialists + representation can be nice, but we've already built two ancient wonders.
Pholk's also already got a boat out (though empty--easily fixable).
Frank's got Splimesylvania hooked up on the trade route, with the silver mined and nearly hooked up. Though I have to seriously question building a forge in Green Dot. Maybe later when we mine the hills, but it's a one-hammer town at the moment. (Granted, 1 happiness with forge + silver is nice, but it won't happen for a while.)
Splime's 2 turns away from having the forge in the capital, and close to having the silver hooked up in his namesake.
Conclusion:
To me, Frank's save has a lot going for it. I'd vote for it right now, but I've not read anyone else's arguments. If I did inherit Frank's save, I'd first switch production in Green Dot and would consider changing research paths.
My $0.02
Edit: Sorry Splime, I failed to notice your settler. Strong point to consider.
Edit2 : Just to reitterate, WTF, Pholk? Who taught you how to count?
