Yes, it is a great album, but I kind of prefer the trippier stuff like Meddle. Most of my favorite PF songs are scattered throughout different albums, but I haven't listened to them much since high school.
Anyhow, I hear you. And again, I'd rather not pick just one. The first and best answer is "three-headed" or some other variant. At least right now. But I keep seeing fans defending their guy, and often with cherry-picking. The vast majority seem very resistant to the idea that their favorite might not be "the One."
Every fandom has their "super fanboys." We all know the resident Roger hyper-partisan, but I can think of two Rafa fans that are similar in degree. I'm not suggesting you or AP or Kieran are anywhere close to that level. But it is a matter of degree, no? I try to be as unbiased as possible, and I think Game even suggested I am over-compensating. Maybe he's right. But I can notice my own bias for Roger creeping in and I try to adjust accordingly. I don't have a bias against Rafa or Novak. I like them both, and about equally (in different ways).
I'd like to be able to say that my guy is the GOAT, but it doesn't matter all that much to me. Roger is one of the greats, and always will be. It doesn't lessen my enjoyment of him to think that, just maybe, he has been equalled or even surpassed. I mean, I hope we see someone, someday, that surpasses all three! Or maybe not, as a single player winning 25 Slams sounds kind of boring!
I actually don't have a super strong opinion about this, other than that all three great, and the question is open for discussion. In the end, though, I'm more interested in coming to something that feels truthful more than vindicating my guy as the best. Maybe it is impossible, as you suggest. But it is fun to think about, at least until it devolves into partisan squabbles.
As an aside, it is funny, monfed blaming me for being a Roger hater. That seems to be common these days: any disagreement with the party line is interpreted as betrayal, and the person disagreeing as some kind of secret agent of the other side. For example, I've traditionally been on the left politically, but there are a few issues that I disagree with the left's party line, and I always get accused of being supportive of Republicans. And around and around it goes. I'm not a big fan of groupthink, in any context!
