mail client thunderbird or outlook 03

which one do you prefer n why? I'm using outlook right now because i like the calendar feature and its ability to sync w/ my mda

I use outlook 2003 b/c I like the features and I'm used to it. I tried thunderbird and it was o.k. It's a decent free mail application. I'm just partial to outlook.

Things I like:

reading pane
calendar
to do list
junk email filter
layout

I prefer Thunderbird since M$ products(le.g. IE) are often chosen by hackers and other nefarious users to attack and exploit.
Afterall, there are more users of Outlook than any other email clients.

Most importantly is the built-in Spam filter, it is second to none.

Plus, the many plug-ins, themes and extras that are freely available is quite the bonus.

I like Thunderbird as well but have never used outlook 3 .
