Welcome to the forum!
The best choice will depend on the features that you want. The 3805 is a nice receiver, but it is older and doesn't have HDMI connections. If those are important to you, then I'd say pass on the 3805. The 1910 has HDMI connections but no pre-amp outputs, and if those are important to you, then you might need to look at different receivers than those two.
If you don't care about pre-amp outputs, then I'd recommend the 1910 out of the two that you listed. HDMI is becoming more and more prevalent, and the 1910 would probably be easier to sell in the near future.
