The only guard I pick over him with strong certainty is MJ.
I think the error bars for Jerry West are wide enough, that you could get him to being the 2nd best guard peak ever. In particular, I think appropriately gauging his playmaking and defensive value would be what decides this.
First off, I think West is one of the 5 greatest scorers ever.
From 64-66 in the PS, Jerry West averaged an inflation adjusted 29.6 pts per 75 possessions (rTS% of 7.3%). Some other notable scoring peaks from guards:
Kobe (07-09)-Inflation Adjusted 30.5 pts per 75 (rTS% of 4.1%)
Kobe (08-10)-Inflation Adjusted 30.4 pts per 75 (rTS% of 3.9%)
Kobe (06-08)-Inflation Adjusted 29.2 pts per 75 (rTS% of 4.8%)
Dwyane Wade (07-10)-Inflation Adjusted 30.6 pts per 75 (rTS% of 4%)
Dwyane Wade-Inflation (09-11)- Inflation Adjusted 29.5 pts per 75 (rTS% of 5.5%)
Dwyane Wade (06-09)- Inflation Adjusted 29.1 pts per 75 (rTS% of 5%)
Dwyane Wade (05-07)- Inflation Adjusted 28.4 pts per 75 (rTS% of 5%)
Curry (15-17)-Inflation Adjusted 28.8 pts per 75 (rTS% of 8.6%)
However, I think what makes me put West above these guys, because of the era he played in where offenses and scoring in general were less efficient. That means that every extra point per possession, and 1 TS% above league averaged much more in terms of value because of how scoring was compressed. Margins were compressed and therefore a point per possession or a TS% point mattered more in the 60s than in modern days.
I think this shows up in a metric, such as ScoreVal (ScoreVal = Scoring value, an estimate of a player’s points per 100 impact from scoring only), which attempts to take in account a player's environment. Including only 1 stretch per player, Jerry West has the third highest 3-year PS scoring peak ever per ScoreVal.
3-year PS ScoreVal
Jerry West-3
Curry-1.9
Kobe-1.6
Wade-1.6
I think the bigger question is what type of playmaking value you think West compared to other more modern guards, as back in West's day it was harder separation through creating for teammates, due to it just being harder to create-less spacing, stricter ball-handling rules, less passing angles due to congested spacing, harder to drive, etc. West was a great playmaker for his era, but how he does compare to some of the best playmaking guards for the modern era is perhaps a bigger question. However, West could really pass;
"West averaged 6.1 assists per game (stellar numbers for a shooting/combo guard) throughout his best scoring seasons of 1961–62 through 1969–70. As his scoring took a downturn throughout his twilight seasons, West’s assist per game averages in the following three seasons increased to a very remarkable 9.3 as he served as the lead facilitator on some of the best offenses in league history at the time"-Rohan Kamat

I feel as if West was likely at least an all-nba level guard, based on the info we had. But there is perhaps the possibility that he was an all-time level guard. We sadly, don't have defensive stats for most of West's career, but he really did seem to fit the billing. West was a great shot-blocker with a 6'9 wingspan, and could be seen blocking other guard's jumpers on more than a few occasions.
But this undersells him, as he perhaps is one of the more disruptive perimeter defenders ever; one piece of information I find interesting is that Jerry West in his final season (1973-74 season) led the entire league in steals per 75 possessions, at 3.1 (inflation-adjusted). It was only 31 games, but I wonder if an older West was capable of this, I am curious what a younger, more spry, and less-injury prone West might be capable of. As I mentioned, I think offense was generally worse in West's time, and the rules allowed for more impactful defenders. I don't necessarily think it is just the bigs that perhaps saw their value as higher than ever, but rather I think it is possible guard defense was more impactful then as well.
It is possible that West challenges up the best guard defenders of the modern era (or maybe more???), while also being a top 5 scorer ever, and not being a black-hole on offense. And that to me is enticing enough to see the possibility of him being as high as #2 in a guard's peaks list.
