Yes, both of those champions are alright for general content, though probably not targetted specialists. It looks like you have quite a few other legendaries though so I wouldn't dwell specifically on these two. I assume that you acquired this account by other means, based on the amount of champions you have and the general low knowledge
The bigger problem that I see is that the speed of these 2 champions are much too low. The boots that you have on them wouldn't have speed as their primary stat, and unless you are going for specific builds, every one of your champions should have boots with speed as their primary stat. This is without exception.
I expect this will be why they are not getting much damage out, or dying, because they cannot actually cycle around to do anything. You might want to spend some time focusing more on the gearing aspect of champions
