Well, all of those besides the £ have a nice symmetry. But it's nothing really annoying, neither for it not for the Ƀ.

Arguably, that's actually a messed up E rather than a C.

I think they all have clearer visual differentiation and generally are more aesthetically pleasing than Ƀ

Not to mention that traditionally Ƀ is pronounced as 'v'.

Traditionally maybe, but only by a small minority (of linguists?)
