Which looks more like a classic lava lamp?

The 14.5in Lava Lamp Plated Crimson. Black wax in red liquid with a chrome base and cap is the traditional look.

How long until the wax starts moving?

The Urban Shop states 1 to 2 hours of warm-up. The Crimson does not state a warm-up time, but wax flow depends on the globe heating up.

Only if you want the chrome finish and the black-and-red color scheme. Otherwise the Urban Shop does the same job for about $19 less.

Do both plug into a standard outlet?

Yes. The Urban Shop uses a plug-in power adaptor with an on/off switch, and the Crimson plugs into a standard wall outlet with a 25W bulb.
