It's a mixed bag.

Firefox uses far less memory per tab, but still chugs down more memory with time. Chrome uses metric shit-tons of memory, but its multi-threading allows individually killing tabs (or just massacring them in bulk if necessary, which it is).

When memory's tight, Firefox seems to bog down as a whole, while Chrome gets boggy on individual pages (and you can kill/reload these as needed).

I find myself using both though I'll fairly routinely go through and kill off Chrome tabs, and periodically restart Firefox, to keep memory management reasonable.

Firefox's tab and state management is far superior to Chrome. Chrome plays better with some advanced sites (notably Google's own webpages, surprise, surprise).
