I have experience of both the new Keydge and the hopsack Vetra so hope this helps.

I like both but they are very different animals. The Keydge is closer to a proper jacket whereas the Vetra is very basic workwear so you miss out on certain details.

The navy Vetra hopsack jacket is superb. I have a vented version and, unusually, the quality is much better than the price point. My local tailor did a slight alteration on the collar and also steamed a subtle roll down to the middle button. I  liked the jacket so much I would of also purchased the ecru version but I have a previous seasons Vetra that although unvented is very similar. Last Autumn I went on to buy the olive micro cord that's  also really nice.

I purchased a new Keydge Seersucker jacket about three years ago. Although it's the Ivy cut the lapel was slightly wider than previous. Once you add on the duty it wasn't cheap. I have subsequently had a load of swatches from the company but didn't take it any further down to cost.

Whilst JS has attempted to replicate the Keydge I would suggest that the fit isn't quite as good. It feels slightly narrower. On positive note that are trying out better quality materials such as the hopsack.

My wife who is fluent in French had along conversation with the guy.
