Wow, based on my experience with Elements, it is WAY faster to build a website with Elements than the Classic/Stacks combo. But more importantly is is WAY more user friendly and intuitive.
It pains me to have to go back and use Classic/Stacks.
I have just been forced to create a brand new site from scratch with Elements and it was incredible how fast it came together, and it ended up looking good to boot.
I’m now in the process of porting a site from Classic to Elements and it has taken an amazingly short amount of time.
The last thing I would call Classic/Stacks compared to Elements, is user friendly!
