So I was doing this comparative study between the application security model between android and now I need a benchmark for it to compete against. The problem though is I am pretty new to mobile application development and barely know the names and probably used a phone or two in the process with each of the OSes. Now the dilemma I am in is, which OS should I pitt against the Andorid to compete with for a security model study. At most I can pick two because I literally will not have the time to complete developing applications for all the Operating Systems in the market to do a comparative study.
Which one would be the best choices according to you? (Please elaborate as to why its a worthy competitor).
