Conjourers (the most common flavor of specialist wizard due to the broad versatility of the school) have Immediate Magic (Abrupt Jaunt) which fixes the snatch problem very nicely.
As I said, different characters have their strengths.
In core only, Dimension Door is a 4th level spell that ONLY has a V component, which means you can cast it in a grapple with a relatively simple Concentration check. Dim Door out of range (what, 800ish feet), note that Spot checks impose a -1 penalty per 10 feet, and run like a SoB under the cover of your -80 cover.
There is a reason most wizards keep one or two D-doors in their back pocket. Otherwise, flying snatchers can be deadly.
I swear I'm not just a mindless wizard apologist, but there is a reason wizards are ranked as Tier 1. ... Fighters have their uses.
We are not in disagreement.
Wizards are extremely powerful. In general, wizard > fighter, in most circumstances. However, I would definitely prefer a wizard and a fighter working together over two wizards. With a wizard backing him up, the fighter doesn't have to worry as much about adverse battlefield conditions or nasty spellcasting combos from monster casters; he is then able to demonstrate his capabilities fully.
I believe the 3.5 fighter is underbuilt compared to most other classes. However, I also believe just as certainly that he is still the best *fighter*. To be truly irrelevant, a class has to be beatable at its own game. It's very difficult for a rogue or a paladin to say, "whatever comes our way, I'll find a way to damage it," but a fighter typically can. A cleric or wizard can hack most scenarios, but they can expend far fewer resources doing so if they can bring a fighter or barbarian to bear against hard-hitting opponents. Rogues don't really fight Large or Huge opponents so much as escape them, or finish them off once they have already been rendered ineffective due to grease/blindness/etc. A wizard and cleric team can bring down dragons, but missteps can be dangerous.
It's much the same as the AD&D thief. It was a weaker class, but it was really better if you had one in your party. Fewer knock spells means more magic missiles, and that makes everyone happy.
Wizards can summon monsters, but if they can buff the fighter, the result is better than either a summoned monster or an unbuffed fighter. See how that works?
