What sorts of use cases? My Thunderbird experience doesn't mirror this at all.
I've found setting up complex filters to be easier to set up in Gmail. Gmail's search is also much faster and it's results more relevant with huge mailboxes.
Gmail also lets you create calendar events from keywords in messages, which Lightning didn't do last time I used it, iirc. I admittedly haven't used Lightning very much; I found that syncing Google Calendars in Thunderbird had a nasty tendency to lock up the app.
