Well, as I said I am not very experienced BUT...
I am using them in an f/5 SW600 Newtonian. On planets they are nice and crisp...under a nice still clear dark sky I can use the 3.5mm on jupiter and it remains crisp. I have noticed that at the periphery of the field there is a small amount of aberration, but that does not bother ME as compared to my old EP's the improvement overall is worth a bit of loss at the periphery. I have little to compare them to, ie. havent looked thru any other EP's but my own.
Likewise on the moon they give really crisp views, superb magnified views.
For deep sky, I wouldn't mind a wider field of view than that afforded by the hyperions, but as i said the crisp views compared to the SW EP's that came with the scope outweigh this. On a good night I can see greenish/bluish hues in M42 through the 13mm.
I think I can see a bit of comma, but that is probably more related to the fact that I am using a Newt, rather than being caused by the eyepieces.They Hyperions are quite bulky and heavy compare the plosyls.
When I first got them I had trouble as I tried to use them in a 2" focuser, I found that to focus I would need a focal extender. But with the expert guidence from those on this forum I was advised to forget that, use the 1.25" adapter.
