Stare at the numbers: First, M.R is more expensive than Armor, of course, so if we compare the defensive contribution of the stats of both items, both items are at the same height with 900 gold worth of Armor and Mr respectively. Now on the offensive stats, Zhonya's offers 2175 g worth of Ability power, while Maw offers 1925 g in AD damage. However, it also has 10 armor pen, so it totals for a 2325g of damage, this means that damage wise Maw offers a greater advantage. Finally, substracting the value of the stats we get the cost of the passive of maw and active of zhonya's, Maw's passive costs only 25 g while Zhonya's passive costs 425g.

WHile the difference doesn't seem that huge considering the ridiculous utility of zhonya's, Maw of malmortious has a much muich MUCH MORE EASIER BUILD PATH, suitable for an early game item. The final cost of it is 850 and the costs of its path are between 350 and 450 gold. Zhonya's meanwhile has two expensive builds:  1050 Final cost and a 1250 item on the build path. That greatly hinders your early game for a rush item because of the times when you would be saving gold and wouldn't progress in your path. Meanwhile you will always progress on your build path while rushing Maw.

That the shield scales off MR isn't that much of an argument, shielding ~375 damage early game is HUGE,

Would you realize how impossible is to kick a Maw of malmortious assassain out of lane, for not to say even try to all in if you get him low enough. On the other hand, zhonya's mages can still usually be kicked out of lane by enough good trades.

Finally and the most important of all points, Zhonya's lacks two of the stats that are a essential for mages and that make rushing zhonya's a huge pain: SUSTAIN AND SPAMABILITY, in stats this means MANA/REGEN AND CDR. Rushing zhonya's prevents you from getting early game damage, spamability and the ability to stay in lane. As using your spells not only to farm but to poke and avoid dying wastes a lot of mana, mages lose a lot of gold in last hits because they need to save their spells and mana and be extremely efficent with them, they usually get outpushed and their turret steals from them a lot of minions. So your "just 7 minions" theory is awful.

In the other hand, Assassains and AD champions overall are more of All - In kind of champions and usually do not have huge mana problems. Sustain isn't really needed for assassains, Mana in some but they can overcome their mana needs and last hitting overall is easier with their AD. CDR is natural with the other items they buy.
