I've had the Semi Apo, Fringe Killer and 495 Longpass with a 152mm F/6 and ended up keeping the 495.

It cut the most CA but does give a yellow cast, most noticeable on Luna and Jupiter but you soon get used to it.

For me it seems to tighten up focus and brings out detail, I was seeing feint companion stars I was not seeing before.

The SA is more neutral but cuts less CA and the FK cuts a bit more but not as much as the 495 and also imparts a yellow cast.

There's no right or wrong rather what you personally prefer.
