Tudor is just Diet Rolex

I was chatting with a friend, and of course we discussed time pieces, the obvious subject of Rolex vs. Omega came up (we happen to love both, and have pieces from both brands), but somehow he asked me about the Pelagos.
I know the history of Tudor, but it is not a brand that I have bought before (the Harrods looks very cool, would I buy it? No.) so I said ‘hmm not sure never had it on wrist…’
To which his response was ‘I don’t blame you, Tudor is just a diet Rolex.’
I do see the similarity in case and dial designs…and of course the history behind Tudor, but where do you stand on Tudor, is it a diet Rolex? Or is it its own brand with its own style, and history?
