Which feature would that be?
here the most important I have seen:
I have a gmail account with IMAP enabled.
I'm used to have a local copy of important emails
and related answers threaded together;
In kmail I had some filters to automate the copy of these messages
a Filter in thunderbird can automatically work only in Inbox,
this means I cannot copy my sent email in my local folder
(often I wrote email from a web browser,
so I cannot copy emails in a different folder at sending time)
- (still under investigation) with kmail I was able to download only the emails
not read from the previous connection
(IIRC gmail remembers the date of the last downloaded mail)
- kmail allows you to decide which prefix declare an answer, so that the answer will go in the mail thread
i.e.
mail subj='hello'
answer1 subj = 'Re: hello'
answer2 subj = 'R: hello'
thunderbird seems unable to understand that answer2 is related to mail
