Symentac Vs trendmicro

I m using trendmicro for last 3 yaers.I have also use Symantec before.But virus definatin of trend micro is much better than symantec.and also the the hardware utilisation specially RAM is much lower than Symentac.It has better management console than symantec.
the client console is also a better one.So i go for trendmicro
