Now, a better phrasing and framing of the conversation (though captured in the poll) could have been lower order batting, vs the cordon vs the supplementary bowling, with emphasis (as required) on the most critical aspect of each, no. 8 vs, 2nd slip, vs the 5th option. But ultimately the groups...
Results would have been mostly the same, but eliminated some of the questions up front. But it was very much in the poll.
Cordon vs tail vs back up bowlers is kinda straight forward.
Yes you don't want a capitulation, and want the tail to wag, someone to hang around with the top order as required, but the further down you go the value drops considerably, and the less batting is factored into selection (if at all).
The 5th bowler is key, after that it's just about who can be called upon in a pinch.
The codon though is important 1st through 3rd (through 3rd is in place the least), if not gully as well.
Edit...
I had an entire summary written, but literally talked myself out of it as I was writing.
Twice....
Every metric gives me a different result.
The position I'm least likely to have to prioritize or select in any XI is the no. 8 (simply because a all rounder at 6 is normally a must).
All rounders also weren't a feature of many of the greatest modern teams, though Australia did have decent batting depth, and Marshall had some match winning knocks. None had high use 5th bowlers, Viv wasn't great, though Harper seemed to bring a boost when he was in the team, Waugh was past his best and Symonds was a sporadic presence at the end of the dynasty. Yes Jacques was there for SA, but he too was well past his bowling best in 2008.
Do great teams need either all rounder? I would suggest vs top end opposition or close contests, yes. Especially that 5th bowler when you're not blowing through the opposition.
On the individual perspective, each have their detractors.
Some have questioned the volume of chances to the 2nd to justify consideration, while most no. 8's in critical situations or challenging conditions are not nearly reliable, and finally every over your 5th option continues to bowl, it's an over your front liner isn't. There is an inherent drop off in quality. (AT scenario, you don't want Sobers bowling as many overs as the front line attack)

@subshakerz and I had to sit and create a world XI to take on the Europans, we would generally settle on 9 and would compromise to each get our guy in.
We've argued about this and while I believe that vs a comparative attack his batting contributions would be minimal (especially on result pitches), he believes that over the course of a series, in at least one match he would have a match saving innings.
While I know that with that bowling attack, Sobers would get multiple opportunities and half chances to complete chances. If every run is vital, every wicket is more so. While neither of us wants to have Sobers bowling too many overs, it's accepted that it's essential to maintaining the bowlers health through the series.
So I've asked some if the longest tenured and most respected posters on the forum and they unanimously went cordon, lower order and supplementary bowling.
Mr. Kimber on the other hand went cordon, supplementary bowling, then lower order batting.
Grok (for what it's worth) went cordon, lower order batting, then supplementary bowling, (for average teams, great teams and AT XI's)
So I think I have it, finally.
While the 5th bowler is the only position of the three that's directly mandated into team selection, and passively is crucial to the functional rotation and viability of an attack, it is a passive role, and they don't feature actively in many results. Grok calls their role moderate, while the other two are high (importance).
For me personally, even though in a couple years my AT pace attack may be Marshall, McGrath and Bumrah, for now Wasim, Marshall and Warne still constitutes a good 8, 9 and 10, who while wouldn't lead a counter attack, are capable of sticking around with a top order bat. And while the top order and a strong no. 7 makes it less of a priority, it's always preferable not to have a full tail of complete rabbits.
From any perspective, it's imperative to take your chances, and it's been a feature of the game since fast bowlers started to rule the roost. So be it the Australian squad from the early to mid 70's and all the genuinely great squads since, they all had AT cordons... The WI just lost a match because they forgot how to catch, one of the biggest factors in the victories of the BGT was the catches dropped by the Australians in the cordon, same for the 1st test of the current series.
In an AT XI, the one that would be most critical is likely the one standing at 2nd to the greatest pace attack ever assembled and at 1st to the leg spinning Warne.
Even today I trust and value a Markham / Brook at 2nd / 1st more than I do a batting Woakes / Jansen / Cummins or even any of the plethora of 5th bowling options that exists around the world today.
