Good summary, and some fair points.
I still think though, it's much easier to win titles and trophies whilst playing defensive tactics. It's not a criticism, but as you rightly point out, it is a good reason some will choose Pep. Football is supposed to be entertainment.
A certain Brentan said something similar to you.
And statistics does not back up your claim. Take a look at the recent CL winners:
2013/14 - Real Madrid (4-1 win over Atletico)
2012/13 - Bayern Munich (2-1 win over Dortmund)
2011/12 - Chelsea (penalty win over Bayern, parked a bus. A lot of the players in the team were signed by Mourinho anyway)
2010/11 - Barcelona (3-1 win over Man Utd)
2009/10 - Inter Milan (2-0 win over Bayern, Mourinho)
2008/09 - Barcelona (2-0 win over Man Utd, ugh)
2007/08 - Man Utd (penalty win over Chelsea, boring game but we were never defensive)
2006/07 - AC Milan (2-1 win over Liverpool, drab match, not sure how to rate Milan but they did blew us away with some Kaka magic, so I don't think they are that defensive)
2005/06 - Barcelona (2-1 win over Arsenal)
2004/05 - Liverpool (3-3 Milan, worst champion in a long time but were Liverpool defensive?)
2003/04 - Porto (3-0 win over Monaco, Mourinho)
So in the past 11 CL winners, only 3 teams were truly defensive and they were all Mourinho-related. So it really isn't as easy to win titles and trophies by playing defensive football.
Even if you do not want to consider solely on CL but on league titles, EPL titles were mostly won by the best attacking team (rated by goals scored).
2014/15 - Chelsea (2nd best offensive record, best defensive)
2013/14 - City (best offensive record, 2nd best defensive)
2012/13 - Man Utd (best offensive record, 5th for defensive)
2011/12 - Man Ciy (best offensive record, best defensive)
2010/11 - Man Utd (best offensive record, 3rd best defensive)
2009/10 - Chelsea (best offensive record, 2nd best defensive)
2008/09 - Man Utd (2nd best offensive record, best defensive)
2007/08 - Man Utd (best offensive record, best defensive)
2006/07 - Man Utd (best offensive record, 2nd best defensive)
2005/06 - Chelsea (best offensive record, best defensive)
So the team with the best offensive record won the league 8 out of 10 times, while the best defensive team only won 5 out of 10 (3 of them are when the team are the best in both anyway). It is a myth that it is easier to get result with defensive tactics.
