Bleach isn't really worth watching. You should skip it entirely. Considering the collapse in popularity and the way Jump pulled the plug on it the rest of it is unlikely to ever be animated. I would say read the manga but there was a lot left on the cutting room floor. The ending is very disappointing.You can skip 50 percent of bleach and be fine. You can skip 30-40 percent of Naruto and be fine as well.
The main character's powers are completely revamped and teased but never actually shown. He doesn't get a true proper fight after his powers get that revamp and you don't get to see what he's capable of. You don't even really get to see his bankai in action either.
