#3 John Cena (13 titles)
John Cena entered 2010 as a 7-time world champion. In the decade since he has more than doubled that tally. Cena won the top prize of the WWE on 9 more occasions, defeating the likes of Batista, The Rock, and AJ Styles to do so.
Aside from his ridiculously consistent stay at the top of WWE's mountain, the Leader of the 'Cenation' also held tag team gold for a combined total of one day, with David Otunga and The Miz.
However, the thing that fans likely remember the most from Cena in the past decade might be his run as the United States Champion. He conducted weekly open challenges, putting on excellent title defenses against various up-and-coming stars like Sami Zayn and Cesaro.
That is the legacy that John Cena leaves us with, as his WWE career is slowly coming to a permanent end.
#2 Kofi Kingston (14 titles)
Kofi Kingston had a crazy decade for sure. He started 2010 near the top of the card, but a miscue in a match involving Randy Orton sent him tumbling down the card. And thus began his dominance of WWE's midcard.
During a period of three years, Kingston won a couple of US, IC, and Tag Team Titles each. But a move at the end of 2014 changed his career for good, as a 'New Day' dawned on him.
As part of the incredibly successful New Day, the Ghanaian Superstar enjoyed seven reigns with the tag titles, including a record-breaking 483-day stint. But Kingston's greatest moment of the decade was his WWE Championship victory at WrestleMania 35, without a doubt.
A steady first half of the decade was followed by a spectacular second half, showcasing Kofi Kingston's incredible persistence over the years.
