Joseph Audio Pearl compare to Genesis 5.3

Has anyone compared these two speakers? Is so opinion please.

Does anyone have any suggestions for a center channel for either the Pearls or the the JA Pulsars? (Besides the obvious answer of another pearl or pulsar). ..
I would definitely stay with Genesis.
Although I have not heard the Pearls, every time I get the upgrade bug, I end up staying with my 5.3's. Their support is also 2nd to none.
How about Genesis 5.3 against the Sasha.
It's rather listener choice, but the value would still dominate with Genesis.
