It's not so simple to be honest. Venusaur's special attack is only slightly lower than Charizard's, Charizard is faster but Venusaur is bulkier. the difference is that Venusaur's bulk and moveset allows for stalling. Blastoise falls a bit behind because his stat's are more defensive, but his moveset doesn't really help him out with a defensive build.
Same thing applies with Johto starters, although Meganium is the bulky one so it's moveset actually fits for stalling which is great. Feraligatr's physical attack is huge, Thyplosion has around the same special attack as feraligatr's attack and is faster but Feraligatr is bulkier.
So basically your picks are just as extreme as mine regarding offensive power.
