I may have to rethink the Betatrooper. I was a bit too fast to dismiss it. It has a similar profile to the Shikami and Hulang but is much better optimized by not wasting points on close combat ability while lacking a marker state or smoke. 6" cautious moves and 6" climbs are pretty great. Also, unlike the other two units you've got access to heavier guns such as the multi rifle or spitfire. On second thought, I think your right. The Betatrooper is probably going to be played a lot more than the Shikami and Hulang.
