Tougher draw in 2011 (Tsonga was better than any of his opponents until the final in 2019) and much better display in the final. He was two sets to love up against prime Nadal after an hour and a bit, that is simply astonishing.
He also returned and moved better that year, so his level was definitely higher.
His highest level at Wimbledon, however, was in 2015. I still think that the matches against Cilic and Federer were his best ever performances on grass (serve, return, movement, ground-game...everything worked perfectly for him).
