It's certainly different. And while the loss of some elements does seem to reduce the necessity of certain strategic elements during the movement phase, the new combat phase rules just added an all new strategic element that can really screw you over if you make the wrong call at the wrong time. So many combat units that were let down by their initiative values are now viable again.
But for me the biggest change is probably how AP works, going from fixed values to modifiers is a huge improvement. In the previous edition, the majority of power weapons being AP3 meant they were useless as soon as someone donned a terminator suit. Now though, everyone has cause to fear power weapons again. The way it should be.
