That depends, of course. I have to say I am an ACT! certified consultant, so
I certainly have my bias. However, I feel ACT! has a much more user friendly
and customizable interface than Outlook. You don't say if you are
considering Microsoft's Business Contact Manager which is used in conjunction
w/ Outlook, but either way, I still prefer ACT! as a contact manager. I
still use Outlook for the email portion, but wouldn't consider getting rid of
ACT! I'm using ACT! 2007 and Outlook 2003 in combination. ACT! 2007 has
nice integration w/ Outlook - can sync activities w/ Outlook, add ACT!
address book to Outlook, create ACT! contacts from Outlook and attach Outlook
emails to ACT! contacts which ACT! 6 didn't. 6 is obsolete by the way. You
might consider upgrading. My advice - try to do the things you do w/ ACT! in
Outlook for a few months and then you'll know. I don't find it any hassle or
great cost hit to have both by the way. ACT! really isn't that expensive if
you get an upgrade and not even that bad if you're buying outright. They do
have different versions which alter the cost as well. Hope this helps
somewhat.
