I own a luxe 2.0 and used a GT last weekend and this is not being biased. Also keep in mind the GT doesnt have many cases thru it yet. The luxe definitely was smoother and also quieter but also is less efficient although i cant complain about either guns efficiency as they both satisfy my need (get about 7 pods of the luxe). Regarding ergos its all personal preference both feel nice in the hands but the luxe takes it in my opinion. Both markers are absolutely amazing and i would recommend either one.
For the last few months i have been using the dye navigator bag and i absolutely LOVE it! There is a separate spot for all of my equipment which makes it easy to quickly find what you are looking for. Also this gear bag is great for travelling as you have the option to attach the top and bottom half so you have everything together(all your gear + clothing). Finally the quality of this bag is just outstanding and has seemed very durable.
