The cockpit windows may not look right to you because they don't have silver window frames on them. On the BN 727's, they're not supposed to, which is why GJ didn't put them on I guess.
Check out the pics @ airliners.net!
I guess if you want total accuracy, then the GJ ones are good. If you'd still rather have them with window frames, then go Jet-X. Me? I got 'em from both.
