No it's fine don't worry. As to answer your question. Vx Ace has a lower resolution than MV. And believe me, after seeing MV, i tried a vx ace game afterwards and suddenly the graphics didn't seem that appealing to me anymore.
And When it comes to scripting we can't literally say that there's no more of it. Actually, they just replaced the Ruby coding language (which i never heard of before discovering rpg maker) by Javascript, a more popular and one that gives more freedom in scripts.
Overall, I think that MV has more to offer than Vx ace, in both graphics and scripting (customization). - Oh i forgot the lovely Side Battlers creator they implemented -. I do believe that right now, people didn't get used to MV yet, and that's understandable since there's not enough ressources as much as Vx's.
Personally, i wouldn't say that MV is a weak version compared to Ace but that's just my point of view.
