Unfortunately, there's no way anyone can accurately answer this. All cues from every era are going to have variations in how they hit as, even if they're the same design with the same species of woods, no two shafts or butts are exactly the same. I will say, though, if you can find an older one that's straight and hits/plays the way you want, you can't really go wrong. If it hasn't warped by now it probably isn't going to as long as it's cared for properly.
Also, judging a cue's playability by who made the finals or won a tournament with that brand isn't really a good way to look at things. The guys you mentioned could have probably done the same with just about any cue out there. They're just that good and they were playing at the tops of their games at those times. The best player I've ever had the chance to watch in in his prime on a regular basis won the all-around title at The Derby with a cut down house cue paired with a Schon shaft. But, again, there's zero doubt in my mind he could have done that with any cue he was comfortable with. He was simply playing that good at that time.
