2x10 drivetrain and chain crossing I've used to ride with 3x10 setup on my MTB. Now I've got a new one with 2x10 (Avalanche 9R Expert).

The question is: do I need to worry less or more about chain crossing on this bike?

This is not a duplicate since I'm mostly interested in difference between 3 and 2*10 setups in terms of chain crossing
The chain will travel less distance sideways, so less, but still if you are big front, big back, it may still touch the front derailleur. I wouldn't call it something to worry about though.
