I think both are similar but... Coronado after acquisition by Meade is know from bad customer service and if enything is wrong under warranty you may wait monts for repair. Also quality is a lottery, you may get best solar scope ever or something with less than average quality. I don't know it's mechanics but helical focuser is not what I like in refractors.
Coroando has bigger BF but it doesn't matter much. I used B600 for imaging and no vignette occured.
Both have tilting etalons. I owned LS60 and I remember that gives uneven illumination a little but I got used to it
Although I own Coronado gear right now (SM90 doublestacked front mounted), if I were to choose I would take Lunt scope.
It's also possible to double stack it using Coronado front etalon

But! I always recommend front mounted etalons as the most universal solution.

At Polish astronomy forum today was put an advert with Lunt LS60THa B600 for 5300PLN (it's around 1300EUR). Grab a bargain, I can help with a purchase

A price like that I got here in Spain after negotiating.
Thank you very much for your information.
Buy a Lunt,

You are good negotiator You will be satisfied with the scope
