Dual SIM works just the same as any other phone. Just two connection. In most cases the main SIM is your data and the 2nd is just for calls. Some phone do have dual data connectivity, but I never had a need pass the first one unless someone is sending me a MMS text.

In most cases DS version will be cheaper than SS with LTE, but again DS with LTE will be even more expensive.
But, Lumia 950/950XL have processors having on-die LTE, so I think there will be no 3g only versions, neither for single sim nor for dual sim versions. Even, Lumia 550 has LTE connectivity.

There are two levels of Dual SIM support. Dual SIM Dual Standby (DSDS) and Dual SIM Dual Active (DSDA).
The basic difference is that with DSDS when you have an active connection with the network on one SIM, you cannot have an active connection using the other SIM. To the network, it's like that connection is non-existent, and for instance an incoming call cannot make it to your device at all, and would go to voicemail automatically.
It's common for DSDS devices to provide optional automatic call forwarding on the other SIM when they establish an active connection, so that calls to your other SIM will be diverted to your active connection SIM giving you the option of picking up via call waiting.
DSDA devices could have active connections simultaneously.
DSDA devices require two radios internally, which is why they're far less common.
The Snapdragon chipsets could support either mode, but would require second radios to support DSDA. According to the specifications released, the 950 and 950 XL support DSDS, not DSDA.

Quick dual sim question, I've always used 2 sims that are totally different carriers. What if I want to use 2 sims by the same carrier? That will still work right?
The other difference is that the dual sim version has LTE category 4 vs. the single sim which has category 6.

Are you in the US? I just checked their site and couldn't find the dual sim version.

How much of a difference will that make?

It depends if your carrier supports the newer categories. If your carrier does support it, you can get faster speeds from your connection. I don't think US carriers have cat 6 yet, but several European and Asian ones have deployed cat 6 in the past year.
