1 or 2 devices, not a lot of point for dual band then if you ask me. Do your devices support both 2.4 and 5ghz? If at least one of them does not support 5ghz, then again pointless for dual band.
Also keep in mind there are 2 kinds of dual band, ones that can be switched from 2.4 to 5 and others that can do simultaneous both bands.

Essentially my router has two signals per Band at a amplified strength. So yes I found it makes a big difference overall. I easily connect multiple devices at one time and experience no lag or slow down. I only have one device that does 2.4ghz only. I put the others on 5ghz. Any guest that comes over is on the 2.4ghz. Which all of them do 300mb/s anyway. At least my laptops see the two channels and recieve on both at the some time. The USB file sharing is like having another network drive.
To answer the OP's question: YES. Dual Channel makes it better even if your devices are only on 2.4ghz. The added benefit is that later if you get 5ghz capable devices you can have them on that as well and dual channel. The upside of the file sharing can be very helpful.
