Usually when you hear someone state that "SWG sucks now" they are people that haven't played the game for four years.
It was four years ago that SWG went through a drastic change in gameplay which alienated many of the players, many of who never got over the change and continue to spread negativity about the game to this day.
I can't say I blame them, the change in gameplay four years ago was probably the biggest mistake in MMORPG history, but SoE seem to have learnt from it.
They make sure that they listen to the community now and the game is vastly improved from that day four years ago with tons of new content and fun systems.
Dont take my word for it though, or the word of disgruntled veterans from several years past, try it yourself for free and make up your own mind:
