I've never seen the lag (much less "incredible") in any model I've known.

I've indeed seen the over-revving sometimes. That said, how is the over-revving any issue compared to the whole not having to even worry about manual gear shifting benefit?

It's like going to the US on a boat, because airplane food is bad. Yes, it might be, but it misses the whole point of getting there faster, easier, safer and with less concerns.
