[Q] Dual Sim V.S one Sim topic

Hi guys
i want to buy " HTC Desire 816 "
but i want to ask
dose the 1 Sim version get Different from the Dual Sim Version
i mean dose the Dual Sim version get Freezes like the Samsung Dual Sim phones ?
or the hardware get changes from the two versions
or its hard to find the Solving problems for the Dual Sim Version because the dual Sim is not very famous
In general which version is the best to buy?
