Arsenal are obviously one million times mightier. 45 total titles, 13 Leagues, the only unbeaten title since the 20th century, 13 FA Cups, the most titles in the oldest active competition in football history, a bunch of legendary players like Henry, Bergkamp, Vieira, Adams, Pires, Campbell and Seaman. Don’t forget the massive global fanbase with a huge following all around the globe, and a much larger club worth than Spurs. Arsenal have a lot more money too, just looking at financial records prove that. Sadly the owners aren’t very keen on spending it.
Spurs have throughout large parts their history been an irrelevant mid table club at best. 2 League titles, 0 Premier League titles, 8 FA cups and a very small fanbase full of some plastics who started supporting Tottenham in 2016 because they enjoyed the cinderella story of a small clubs rise from mediocrity ( if you can call winnings nothing a cinderella story). Spurs have had a few decent players in the past but nothing close to their nightly neighbours.
Comparing Arsenal to Spurs in a club size context is like comparing Barcelona to Espanyol.
