Interesting thread, these questions are sometimes asked in other sports (one example being tennis). The problem is it's obviously hard to put 2 players against each other from completely different eras. If you put 2013 Get right in a 2021 server vs s1mple he'd get trashed and vice versa. The feel of the game is much different.
So I'm going to put them in order of how they performed in their respective years and I'll just do a top 5:
1. 2014 KennyS - 1.25 Rating. This was a time of very very competitive CS, perhaps one of the most competitive years. The Danes were finally coming into their own, Fnatic super strong, NiP still super strong, French also around and doing great, GuardiaN and s1mple putting up good numbers, viruts frikin pro, and a great NA scene. KennyS just demolished people and entire teams. It felt like every game he was dropping 25+ and literally running around no scoping elite players, CS was fantastic to watch. It also felt like he just did it all by himself and didn't play off his team like the modern day players. Sadly it didn't last long with that early 2015 AWP nerf, so he's often overlooked.
2. 2012-2013 GeT_RiGhT - 1.47+1.33 Rating respectively (I did 2 years for this as CS:GO didn't start till mid 2012). Most people I see on here are like 2019-2021 accounts so probably won't be able to fathom how much he dominated back then. Yes, people were making the transition into CS:GO and he was far ahead, but even by late 2013 you'd bet your inventory on him. If we're talking about peak, it's hard to ignore numbers like that, especially over an entire year.
3. 2020 Zywoo - 1.29 Rating - Doesn't need much explanation, I'm sure everyone here watched that year, magical stuff.
4. 2019/2020/2021 S1mple - Pick any year you like, great player, insane the stuff he pulls out. I say pick any year as I'm happy any of those years would put him 4th on an all time list of CS:GO peaks - just none of those 3 years (so far) was quite as good as Zywoo's 2020, very close though.
5. 2013 F0rest - 1.28 rating. Hard to put GTR up at #2
and forget about forp - felt like he just clicked off heads with any weapon. He also had this 'don't really care if die, just want the round win for the team' attitude - but it actually worked out nuts for him, due to pure mechanical skill. For that particular area (movement, skill and just general understanding of the game) I'd probably put f0rest #1
. F0rest never got #1
on a HLTV top 20, which probably makes you wonder why I put him above the likes of Cold, Olof etc... But that just goes to show how good GTR's 2013 was.
Who'd be coming up next on my list, in no particular order:
FYI for the s1mple fanboys coming for me, I'm considering this like a HLTV top 20 (the entire year) - not 'peak during a game'.
