Which NA Finals was the Greatest of All-Time?

The Team Liquid vs Team Solomid was a great finals and honestly, I thought TSM would win 3-1 but I'm surprised Team liquid actually came back from 0-2 and won but I ask the community which NA finals was/is the Greatest of All-Time?
My favorite NA Finals has to be the 2016 NA Finals between TSM and CLG.

2014 TSM vs C9 ...................... TSM was down 0-1 against a Dignitas team that actually came to play that series, as well as beating TSM in their majority of meetings that split in the regular season, add the fact that 3/4 games went 40+ was a bonus. TSM then had to compete against LMQ constantly being down 0-1, 1-2 to finally win against LMQ 3-2 to face Cloud 9 in the Finals, in which in that series TSM was down yet again, 0-1, 1-2 to finally the Championship against C9 in start to actually start a true rivalry giving C9 not only their first series loss but also their first loses in the post season to boot.

2015 CLG vs TSM ........................... The Faith Age with D-Lift finally winning a Championship with Aphromoo in which was also Dyrus' last split in the LCS. The series was a quick 3-0 with D-Lift getting a Penta on Jinx close to 2v5 with only Double and Aphromoo left standing in Game 2. Also, seeing HotshotGG cry after the series and thanking his team for the win was something special.

2016 CLG vs TSM .......................... Simply....... AMAZING! This was also when NA in my opinion started to actually become a real region and not a garbage region(YES, even I to this day mock NA) but all banter aside, NA in 2016 was so damn competitive. Aphromoo talking trash to D-Lift and saying such win was for Link/Chauster/Nien etc AKA the players that left or was kicked because of D-Lift and getting the win against such was as they say, " LIT " TSM not only had to face Cloud 9 in the first round but also the I believe 17-1 Immortals in the second before facing CLG, and CLG had to face Team Liquid which in some people's minds is the Greatest Semifinals in NA history in an competitive 3-2 series before the story teams faced off.

2016 TSM vs C9 ........................ Like I said about 2016 being the best NA year as far as being "competitive" so was the 2016 Summer Finals and Playoffs/3rd place Series too. TSM eliminated CLG in the second round, C9 then eliminated the humiliated Immortals from a split ago 3-2 to face off against TSM in the Finals.

2017 TSM vs C9 ........................ C9 was down 0-2 against TSM before storming back to tie the series 2-2 however in Game 5 Jensen made/or lack off didn't Ult or used in the teamfight that decided the series.
