Which is better for running four speakers and a sub?

The CT-800.5D. Its fifth channel delivers 400W at 1 ohm or 300W at 2 ohms for a sub, so you need only one amp. The Stinger would need a second amp for the sub.

Which has more power for door speakers?

The Stinger MT-600.4. It does 250W x 4 at 2 ohms and 150W x 4 at 4 ohms, against 155W x 4 and 100W x 4 on the CT's speaker channels.

Is the CT-800.5D worth the extra money?

Yes if you want a sub and four speakers on one amp. At $219.99 versus $119.00, the extra $100 buys a sub channel and saves the cost and space of a second amplifier.

Which works better with a factory head unit?

The Stinger. Its 0.5V to 11V input sensitivity handles low-voltage pre-outs, while CT-800.5D buyers report clipping with pre-outs under 1.5V.

Which is cleaner sounding?

The CT-800.5D on paper, with a 94 dB signal-to-noise ratio against -90 dB on the Stinger. Some CT buyers still report light noise at zero volume.

Do both include a remote bass knob?

Yes. The CT-800.5D ships with a remote bass knob, and the Stinger MT-600.4 includes a remote level control.
