The West Ham man, who had a spell on loan with Birmingham last season, is back in the second tier after making a temporary switch to QPR.
Morrison, who made his home debut for Rangers in Saturday's 1-1 draw against Leeds, said: "It's very different to the Premier League.
"I actually think it's a lot harder in some respects. You get a lot more time on the ball in the Premier League.
"In the Championship you don't get much time on the ball and you have to make decisions very quickly."
Having fallen out of favour at Upton Park following an impressive start to the season, Morrison is hoping Rangers boss Harry Redknapp can help get his career back on track.
"I think it's pretty obvious that he's a really good manager," added the 21-year-old.
"From what I can tell, he is one that looks after his players. I'm just hoping he can get the best out of me."
