labubby,
Let me give you some hard-earned parenting advice (although, if you are truly a bubby, I would think you would be aware of this already as you have more parenting experience than I do).
Do not focus on a list of the “best yeshivos.” The yeshiva you should be searching for is not the “best yeshiva” but rather the best yeshiva *for your son*. Just because a yeshiva is a “top yeshiva” that does not mean that it is necessarily right for your kid. You have to know your kid’s personality, temperament and academic ability. If you send your kid to a “top yeshiva” and it’s not right for him, you’ve lost far more than you gained.
Sadly, I’ve seen parents blindly chase “the best yeshiva” without regard to whether it was right for their particular kid. They either wanted the prestige of being associated with “the best yeshiva” or figured that because it was good for one of their kids that is must be good for all their kids*.
Do me a favor — instead of focusing on “the best yeshiva,” find the one that’s right for your kid. It may turn out that the “the best yeshiva” is the right one — but don’t focus the search solely on the reputation of the yeshiva while ignoring the particular needs of your kids.

* And, yes, I practice what I preach. I have two boys in high school — and they are in two different high schools because they are two different kids with different academic, religious and social needs. The high school that my oldest is in works for him — but was not right for his younger brother. We didn’t even apply to that school for him (and not because we’re not happy with that school).
