I've owned all three brands. The Scurfa I tried on and put it back in the box about 5 minutes later- I sold it within the week. I found it a too chunky and hated the glare-prone crystal.
The Seiko (an SKX009) I kept for about six months. I bought it new in spite of the fact I dislike the date function and it had a day/date. It looked nice but time-keeping wasn't great and the fact it could not be hand wound to get it started were bothersome. It was also a bit thicker than I prefer.
I've owned a half dozen CWC divers and currently have three - a matte 2012 T dial quartz, a 2002 auto and a 2018 no date SBS. I'll likely pare it down to one when I buy a new house in a few years but am currently happy to wear all three.
As mentioned the Zeno PRS-3/4 is a good alternative to the CWC except that the sapphire crystal is prone to glare (as is my current SBS with its sapphire crystal).
