The 3ware uses the 3w_9xxx (in sarge kernels) while the Areca uses arcmsr (not in sarge).
With the arcmsr driver, I grabbed the source from the Areca website and built, with the kernel headers installed, like so:
make -C /lib/modules/$(uname -r)/build M=${PWD} modules
Then copy the module into the appropriate place:
/lib/modules/$(uname -r)/kernel/drivers/...
and run update-modules.
I *believe* the arcmsr driver is now in the upstream kernel (and so in the latest Debian sid kernels).

I've not used the 9550, only the 9500 which works fine. I believe you can have the disks in pass-thru (JBOD) mode but have never used it in this way. When you have an array defined, you only get the array.
The command line tools and the web-server admin/monitor all work fine for both tools.

Go for 3ware if you don't want the admin overhead of maintaining the modules. They're a little cheaper and work well enough.
One difference to note: with the version of the Areca driver I have, there are no syslog/kernel messages when disks die or are removed. Hopefully this has changed in later versions. The alarm is quite loud though. ;-)
