decent mortice door catch reccomendation

[pgrbff]

Can someone suggest a decent door catch brand?
I have just bought a Carlisle Brass and whilst it isn't the worst I've seen it could be better.
When I lived in the UK I always used F Allart at home but that may be over the top for this job

Are Corston any good, they're available in Italy.
