I like heavier suji, 200g and up are my favorites, my besties are 225g. 270mm are good production knives. But keep in mind that a work day (catering) for me frequently involves 60ish lbs of brisket slicing and I've done more 200 lbs at an event. Heavier knives seem to do some of the work for you.
I don't know where the Yoshi is on the weight scale but 160ish grams should be fine for home use. Their gyuto is mid weight, very thin behind the edge and I wouldn't expect the suji to be a great departure from that. I would like to try one myself but there are about a gillion knives I would like to try.
If you're shopping, I'll suggest looking at the "Heijii Direct" thread and pose an inquiry about a suji from him. Had one (until it grew legs and walked off), was one of my favorites, especially for an off-the-shelf knife. And MSCutlery may be able to make you a custom in that price ballpark - if I was shopping with $400ish to spend, I would definitely have that convo.
