I want to replace some 24 pin ROM sockets on a Centipede boardset. GPE has the machine pin sockets for a good price. Are machine pin the preferred way to go by the pro board repairers?

Only neg I see is that some complain about machine pin sockets being much harder to desolder someday.
 
Machined sockets are much nicer, as they make better contact. Less chance of the chips working themselves out.

I'm guessing the difficulty in desoldering comes from the leg size. If you can get a tool like a Hakko 808 desoldering gun, that would probably help desoldering it in the future.

But hopefully there would be no need to remove the good socket? Just the bad ones?
 
Whichever you decide you will be miles ahead of those crappy sockets atari used. It depends on which ones they put on, if its the ones that contact the edges of the ic legs they are good as garbage.
Your going to find a 50/50 split on preference of dual wipe vs machine pin. Personally I think either will work fine and dual wipes are more than good enough.
 
Machined pin all the way in my book, especially on nice original boards, for crappy old bootlegs that I intend to sell on I tend use dual wipes. The only problem with machine pin sockets is they are extremely hard to recover from the board later if you end up scrapping it, plus you have to buy them online to get anywhere close to a sensible price.
 
Maybe i am OT, but could you please upload a couple images of good and bad chip sockets (just to have an idea)

Notice how the pin holes are cups. The wire leads on the bottom are thicker going into the board, so it fills more of the hole in the board, which is why recovery is harder.



Dual wipe (right guys?):
