#1 would be faster due to the faster bus speed more than the CPU speed. First thing I would do is bump it to 8GB for cheap.
Speed is a relative term, it really depends on what you want to do. I would upgrade the ram before throwing Lion on it.
If I have to crack open No. 1 and pay for RAM, my question will become moot.

It has to be said... If you want even better speed and response, get a new one
to also not answer your question, I've personally decided not to upgrade to Lion on my (ancient) Core 2 Duo MacBook w/ DDR2 RAM. It's unfortunately limited to just 3GB and I don't think I'll benefit much from Lion.Obviously, that is true, but it does not answer my question.
Nor does suggesting I add more RAM.

Seriously, as they are currently configured, would there be a noticeable difference?

I did answer your question in the first sentence of my original post.
I upgraded my 2.26 GHz Core 2 Duo MacBook Pro which had 2 GB DDR3 1067 MHz RAM. With 2 GB RAM it felt about the same in Lion as it did in Snow Leopard. Both felt somewhat lethargic, and bringing it to 4 GB RAM didn't help much (since I wasn't a heavy multitasker). What really sped it up was putting in an SSD. With the SSD, it felt like a brand new machine, even with just 2 GB RAM.to also not answer your question, I've personally decided not to upgrade to Lion on my (ancient) Core 2 Duo MacBook w/ DDR2 RAM.

I haven't seen any benchmarks of Lion on 3-4 year old Macs, so it's hard to answer your question directly. At this stage, I wouldn't buy any computer that uses DDR2 memory.
