my absolutely favourite Summer Olympic Sports right now are Fencing and Judo, then Karate, Wrestling and Field Hockey complete my Top 5...
then...
2nd tier (very close to the top 5, had much trouble separating them): Sport Climbing, Slalom Canoeing, MTB Cross-Country races, Swimming, Athletics and Handball (especially the women's tournament)...
3rd tier: Archery, Beach Volleyball, Rowing, Shooting (especially shotgun shooting and the rapid fire pistol event), Triathlon, Taekwondo, Track Cycling...
4th tier: everything not mentioned elsewhere...
Bottom of the pile: Diving, Gymnastics, Equestrian Sports (even if sometimes I like to watch Jumping and the Cross-Country race of the Eventing discipline), Surf, Skateboarding...
special notes: I like Football (I could put it in the 2nd tier), but not the women's side (in general) nor the men's Olympic tournament, which I consider disrespectful of the Games for not being played by the best players of the sport...
and the same it's for Baseball (this would surely be among the top 5, if only...), actually it's even more so, as I normally like Baseball more than Football (but not this farce that's gonna be the Tokyo tournament)...
moreover, I have the same kind of feeling for Golf (even if in this case the best players in the world could be there, if only they wanted to)...I love it (2nd tier...very close to the top 5), but the Olympic tournament is the least attractive of the entire season to me...
p.s. I don't even bother to consider them sports and therefore they are not even in my ranking Artistic Swimming, Rhythmic Gymnastics, Trampoline, BMX Freestyle (and the same is for 3x3 Basketball, even this is a legitimate "sport" to me...just it's not for me)...
p.p.s. (Ice) Hockey still remains my favourite sport overall...also in Summer!
