Some Thai user has compare both already.
You can find the review (in Thai) but it easily to understand from a lot of picture.

I have both. It up to you what you need. Beam or the nice body.
If you prefer the quality of the beam, go to Fenix.
If you prefer the good build quality, Sunway is your answer. It is the best built quality in my collection.
Sunway is easily to carry because of the smaller size.
It very hard to choose only one from them. It up to you what you focus for.
