What looks like better port work?

Im pretty sure i know what response i will get from this but its something i always kinda wondered. I tested it on guys in my shop and they gave me answer's i thought the general consumers would which suprised me. Im going to call this market research its not done to make anybody mad.

from these pictures what looks like better port work what would probably make more power and why? these are a stock valve 700xx head

people like bo please dont comment on this just yet i am curious what general people think, and dont think about to hard just give your first response ewwa, uhh ahh, 1 looks better becuase its shinnyer, 2 is better cause its bigger and shiny, 3 just cause, 4 because its rougher and will do something to the air. you know something simple

1 and 2 look about the same to me 4 does look rough and smmes to have more materieal on the spline where they join toghter 3 looks like it could be polished a bit more but may just be that its a different angle.2 actually looks like the spline (center section is straighter than one if that makes since. there rambling from some one that knows very little about porting.

To me they all look the same... are they just different angles from the same step in the process?

Looks like 4 has the vavle guides ground down further so you might be able to flow more. Give 4 a polish and I'd say that one. I like to know the end result, very interested.
