Refractor Comparison

[Tribal-Wolf]

Can someone give me a rough idea of which size reflector would be comparable for viewing performance to the Skywatcher Evostar 120 refractor? I realise they're different types of scope but I was curious as whether or not a refractor might suit me more.

Please feel free to say so if it's a silly question.

an 8" would easily give better performance and without the false colour
