I had the opposite experience as well -- I tried Page.ly first but could not import any of my sites (which all use a variety of custom post types). Their import process seemed more attuned to vanilla installs. Closing out my billing with them was also somewhat arduous.

WPE has been great so far -- very responsive support -- and their caching handles about 8 million pageviews a month with 600-800 simultaneous visitors and very little downtime.
