I run LightTable and PyCharm both side by side throughout the day as of a almost a year ago and I definitely feel the opposite. LightTable is much more responsive for me.

Although switching to an SSD made PyCharm a lot faster.

That may be the case honestly, I tried LightTable for a few weeks about a year ago and it was somewhat slow, it may well have gotten better.

I tried atom a week ago and it was extremely slow, much slower than LightTable. Almost 30s startup times and it was extremely slow at opening large files and even slower when trying to scroll through them.
