Comparing individual stages from various World Shoots is like comparing individual people in one crowd to another: you'll find similarities if you look for them. Every World Shoot had memorable stages.
The difference comes when you compare the matches as a whole. It's very difficult (nay: impossible?) to build a World Shoot match now that compares in shooting challenges to "the good old days". The two reasons that spring to mind are:
1) The number of competitors. While I don't recall the number of shooters in Bisley, it was no where near the size attending recently (presently it's 1100'ish competitors, plus hundreds of pre-match shooters). The smaller attendance at Bisley meant we shot every day, all day for 5 days. Presently the algorithm is to shoot 5 half days out of 6 full days. With less shooters you can shoot more stages... more stages = more fun.
2) The round counts were higher. Again: I'm working from memory, so I can't give the exact round count, but there wasn't the stringent 3 small to 2 medium to 1 large stage format that is written in stone now. While there were big stages and small stages, it wasn't as rigid and I believe there was therefore more rounds going down range. Presently the Open shooters do 1 reload per day (since there is only 1 32 round course per day at a modern World Shoot). Of course at Bisley, while high-cap race guns did exist, they were in their infancy and (from memory) we were running around 20'ish rounds max per mag, and therefore: more reloading.
Long story short: the old matches were better, but we are currently damned by success and with the popularity of these matches, it simply isn't feasible to get as many rounds downrange as we used to.
On the other hand, there are probably less problems/arbitrations at modern matches, because: a) the officiating is more consistent and b) rule loopholes have been closed and c) we've learned from our mistakes and stage problems that caused us grief in the past have been eliminated.
