GAdv is my homepark and I visited SFGAm back in 2006 and I completely disagree. Toro is arguably the #1 coaster in the world (steel or wood), Nitro is a much better ride than RB, front row on Ka is better than any ride I rode at SFGAm, both have B:TR and S:UF clones, then GAdv still got 2 medium-quality B&M's and a few decent family coasters. GADV also just added a 200ft Skyscreamer and the tallest drop ride in the world, a one of a kind safari attraction which the GP go nuts for, and a package of other flats.
I LOVED SFGAm...it's the nicest SF park I've been to and is quite well-rounded. But I still slightly prefer GAdv altogether when factoring in coasters, flats, and the safari. GAdv is also very nice besides a couple dead-ends, and operations are among the best in the chain.
Your criticisms do apply to SFMM, though. SFGAm and GAdv are probably the cream of the SF crop.
Safari is a capacity nightmare and a waste of time to see something at any zoo, just without the chance of the animals attacking each other. Kingda is a great coaster, I agree with you. But Kilo is just a waste of space... Getting rid of a woodie for a record breaking drop tower and a capacity nightmare. Great. Nintro is just and out and back with more airtime; Raging Bull is for the twists and some air time. El Toro may be great, but the turns at the end seem a bit obnoxious. SFGAdv has great pontential, it's just being operated by the wrong person. In my opinion, there are too many large holes in the park at the moment.
