Decisions, decisions

Hi guy's Iam looking at changing my current keyboard, https://www.amazon.co.uk/TeckNet-Illuminated-Programmable-Keyboard-Water-Resistant/dp/B010O3L3VW/ref=sr_1_1?ie=UTF8&qid=1495273493&sr=8-1&keywords=tecknet+gryphon+led+illuminated+programmable+gaming+keyboard, which i really like, to either a logitech g19s or the g910. what are your guy's opinions of these keyboards?

What are you looking for in a keyboard? I am partial to wasd keyboards, but have quite a few different brands as it doesnt really bother me as much as a mouse.

well I'm not sure, that's why I'm asking the people here for their opinions on the two logitech keyboards I said in the main post
