They both lack the manpower to keep up. I personally don't mind missing on the latest features, but I don't want my software to be full of old security holes that were patched long ago in upstream Firefox. Besides, I have once witnessed a conversation between Palemoon developers and some distro's packagers about usage of palemoon logo or trademark or something like that. The developers spoke in a very entitled tone and it was quite off-putting.
